Question

Trevon made a trip to the recycling plant and back. The trip there took five hours and the trip back took four hours. What was Trevon's average speed on the trip there if he averaged 70 km/h on the return trip?

A) 70 km/h
B) 75 km/h
C) 77.5 km/h
D) 80 km/h

Answer 1

Trevon's average speed on the trip there was 56 km/h.

Step-by-step explanation:

To find Trevon's average speed on the trip there, we need to calculate the total distance traveled on the trip there. Since the round trip took 9 hours in total (5 hours there + 4 hours back), and the trip back had an average speed of 70 km/h, we can multiply the average speed by the time to find the distance traveled on the return trip: 70 km/h * 4 hours = 280 km. Since the distance traveled on the round trip is the same, the distance traveled on the trip there is also 280 km. To find the average speed on the trip there, we can divide the distance by the time: 280 km / 5 hours = 56 km/h.
