Steve traveled the first 2 hours of his journey at 40 mph and the last 3 hours of his journey at 80 mph. What is his average speed of travel for the entire journey?

Komal

First part of the journey:
   - Speed = 40 mph
   - Time = 2 hours
   - Distance = Speed × Time = 40 mph × 2 hours = 80 miles

Second part of the journey:
   - Speed = 80 mph
   - Time = 3 hours
   - Distance = Speed × Time = 80 mph × 3 hours = 240 miles

Calculate the total distance and total time

- Total distance = Distance of the first part + Distance of the second part
  Total distance = 80 miles + 240 miles = 320 miles

- Total time = Time of the first part + Time of the second part
  Total time = 2 hours + 3 hours = 5 hours

Calculate the average speed

The average speed is given by the total distance divided by the total time.
Average speed = Total distance / Total time = 320 miles / 5 hours = 64 mph

Therefore, Steve's average speed for the entire journey is 64 mph.
