Question 204339


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/time}}}
Av s = {{{48/7}}}
Av s = 6.857 km/hr
