Solution

To solve this problem, we need to find the average speed for the entire journey.

Step 1: Find the speed of each leg of the journey.

  • The speed from A to B is distance/time = 200 miles / 5 hours = 40 mph.
  • The speed from B to A is distance/time = 200 miles / 4 hours = 50 mph.

Step 2: Find the total distance and total time.

  • The total distance is 200 miles (A to B) + 200 miles (B to A) = 400 miles.
  • The total time is 5 hours (A to B) + 4 hours (B to A) = 9 hours.

Step 3: Calculate the average speed.

  • The average speed is total distance / total time = 400 miles / 9 hours = 44.44 mph.

So, the answer closest to this is D) 400/9 mph.
