Hey Prudence, good to see you again. Here are the solutions based on the provided graph: 1. How long did it take the person to travel ___ km? a) 100 km Step 1: Locate 100 km on the vertical (distance) axis. Step 2: Move horizontally from 100 km to the line on the graph, then vertically down to the horizontal (time) axis. It took 1 hour to travel 100 km. (Position on graph: (1, 100)) b) 500 km Step 1: Locate 500 km on the vertical axis. Step 2: Move horizontally from 500 km to the line, then vertically down to the horizontal axis. It took 5 hours to travel 500 km. (Position on graph: (5, 500)) c) 800 km Step 1: Locate 800 km on the vertical axis. Step 2: Move horizontally from 800 km to the line, then vertically down to the horizontal axis. It took 8 hours to travel 800 km. (Position on graph: (8, 800)) d) 750 km Step 1: Locate 750 km (halfway between 700 km and 800 km) on the vertical axis. Step 2: Move horizontally from 750 km to the line, then vertically down to the horizontal axis. It took 7.5 hours (or 7 hours 30 minutes) to travel 750 km. (Position on graph: (7.5, 750)) e) 300 km Step 1: Locate 300 km on the vertical axis. Step 2: Move horizontally from 300 km to the line, then vertically down to the horizontal axis. It took 3 hours to travel 300 km. (Position on graph: (3, 300)) f) 250 km Step 1: Locate 250 km (halfway between 200 km and 300 km) on the vertical axis. Step 2: Move horizontally from 250 km to the line, then vertically down to the horizontal axis. It took 2.5 hours (or 2 hours 30 minutes) to travel 250 km. (Position on graph: (2.5, 250)) 2. How far did the person travel in: a) 1 hour Step 1: Locate 1 hour on the horizontal (time) axis. Step 2: Move vertically up from 1 hour to the line on the graph, then horizontally to the vertical (distance) axis. The person traveled 100 km in 1 hour. (Position on graph: (1, 100)) b) 1 hour 30 minutes Step 1: Convert 1 hour 30 minutes to 1.5 hours. Locate 1.5 hours on the horizontal axis. Step 2: Move vertically up from 1.5 hours to the line, then horizontally to the vertical axis. The person traveled 150 km in 1 hour 30 minutes. (Position on graph: (1.5, 150)) c) 3 hours Step 1: Locate 3 hours on the horizontal axis. Step 2: Move vertically up from 3 hours to the line, then horizontally to the vertical axis. The person traveled 300 km in 3 hours. (Position on graph: (3, 300)) d) 4 hours 30 minutes Step 1: Convert 4 hours 30 minutes to 4.5 hours. Locate 4.5 hours on the horizontal axis. Step 2: Move vertically up from 4.5 hours to the line, then horizontally to the vertical axis. The person traveled 450 km in 4 hours 30 minutes. (Position on graph: (4.5, 450)) e) 5 hours Step 1: Locate 5 hours on the horizontal axis. Step 2: Move vertically up from 5 hours to the line, then horizontally to the vertical axis. The person traveled 500 km in 5 hours. (Position on graph: (5, 500)) f) 2 hours 30 minutes Step 1: Convert 2 hours 30 minutes to 2.5 hours. Locate 2.5 hours on the horizontal axis. Step 2: Move vertically up from 2.5 hours to the line, then horizontally to the vertical axis. The person traveled 250 km in 2 hours 30 minutes. (Position on graph: (2.5, 250)) How long will it take to travel 275 km? Step 1: Determine the speed from the graph. The graph shows 1000 km traveled in 10 hours. Speed = DistanceTime = 1000 km10 hours = 100 km/hour Step 2: Use the speed to calculate the time needed to travel 275 km. Time = DistanceSpeed = 275 km100 km/hour = 2.75 hours Step 3: Convert the decimal part of the hours to minutes. 0.75 hours × 60 minutes/hour = 45 minutes It will take 2 hours 45 minutes to travel 275 km.
