Carlos drove to the lake and back.
The trip there took three hours and the trip back took five hours.
He averaged 33 km/h on the return trip.
Find the average speed of the trip there.
:
let a = the average for the trip there
:
Write a dist equation; dist = speed * time
:
dist there = dist back
3a = 5(33)
3a = 165
a = 165/3
a = 55 mph on the way there
