(d) Suppose that to pump the gasoline, pay for it, and walk back to the truck takes you another 45 min. What is your average speed from the beginning of your drive to your return to the truck with the gasoline ?

Text Solution

AI Generated Solution

To find the average speed from the beginning of the drive to the return to the truck with the gasoline, we need to calculate the total distance traveled and the total time taken for the entire journey. ### Step-by-Step Solution: 1. **Identify the distances traveled:** - From the truck to the point where it ran out of gasoline (Point A to Point B): - Distance AB = 8.4 km - From Point B to the gasoline station (Point B to Point C): ...
