An aircraft carrier made a trip to Guam and back.
The trip there took three hours and the trip back took four hours.
It averaged 6 km/h on the return trip.
Find the average speed of the trip
:
Find the distance using the time and speed given for the return trip:
d = 4 * 6 = 24 km
:
We know the total traveled distance = 48 km
Given that the total travel time = 7 hrs
:
Av speed = dist%2Ftime
Av s = 48%2F7
Av s = 6.857 km/hr
