An aircraft carrier made a trip to guam and back. the trip there took three hours and the trip back took four hours. it average 6 km/h on the return trip. Find the average speed of the trip

there

The average speed is 8.0 km/h

Explanation:

We use the data for the return journey to calculate the distance travelled using the constant velocity equation:

s=vt=6⋅4=24 km

Note I didn't change any units so the answer comes out in kilometres.

Now use the distance and time taken to travel to Guam to find the average speed:

v = st = 243 = 8.0 km/h
