Convert 300 litres of water into 500ml bottles. Also, calculate the time taken for a 1500m race with average speed of 5m/s.

Here are the solutions to the problems: Question 1.1.5 Step 1: Convert the total water required from litres to millilitres. From Question 1.1.1, the total water required is 300 litres. We know that 1 L = 1000 ml. Total water required in ml = 300 L × 1000 ml/L = 300000 ml Step 2: Calculate the number of 500 ml bottles needed. Number of bottles = Total water required in mlCapacity per bottle Number of bottles = 300000 ml500 ml/bottle = 600 bottles The total number of bottles needed is 600 bottles. Question 1.1.6 The "total duration of the event" is not provided in the question or the preceding context. Therefore, this question cannot be answered without that information. Question 1.1.7 Step 1: Calculate the time taken to complete the race in seconds. The distance is 1500 m and the average speed is 5 m/s. We use the formula: Time = DistanceSpeed. Time in seconds = 1500 m5 m/s = 300 seconds Step 2: Convert the time from seconds to minutes and seconds. We know that 1 minute = 60 seconds. Minutes = 300 seconds60 seconds/minute = 5 minutes Remaining seconds = 300 seconds - (5 minutes × 60 seconds/minute) = 300 - 300 = 0 seconds It takes 5 minutes and 0 seconds to complete the race. Question 1.1.8 Step 1: Calculate the total time in seconds to dispense 50 litres of water. The dispensing rate is 0.25 litres per second. Time in seconds = Total water to dispenseDispensing rate Time in seconds = 50 litres0.25 litres/second = 200 seconds Step 2: Convert the total time from seconds to minutes. We know that 1 minute = 60 seconds. Time in minutes = 200 seconds60 seconds/minute = (10)/(3) minutes Time in minutes ≈ 3.33 minutes It will take (10)/(3) minutes or approximately 3.33 minutes to dispense 50 litres of water.
