Please help me with a graph of 15:45 to 17:45

here's how to draw the number line for the duration from 15:45 to 17:45.

1. Calculate the duration:

• From 15:45 to 16:00 is 15 minutes.
• From 16:00 to 17:00 is 1 hour.
• From 17:00 to 17:45 is 45 minutes.
• Total duration: $15 \text{ minutes} + 1 \text{ hour} + 45 \text{ minutes} = 1 \text{ hour } 60 \text{ minutes} = 2 \text{ hours}$.

2. Draw the number line:

• Step 1: Draw a straight line with arrows on both ends.
• Step 2: Mark a point on the left side of the line and label it $15:45$. This is your starting time.
• Step 3: Draw a jump of $+15 \text{ minutes}$ from $15:45$ to $16:00$. Label $16:00$.
• Step 4: Draw a jump of $+1 \text{ hour}$ from $16:00$ to $17:00$. Label $17:00$.
• Step 5: Draw a jump of $+45 \text{ minutes}$ from $17:00$ to $17:45$. Label $17:45$. This is your ending time.
• Step 6: Indicate the total duration above the number line as $\boxed{2 \text{ hours}}$.

Here's a visual representation of the steps:

$$\text{Start: } 15:45 \xrightarrow{+15 \text{ min}} 16:00 \xrightarrow{+1 \text{ hour}} 17:00 \xrightarrow{+45 \text{ min}} 17:45 \text{ :End}$$
