Problema Solution
a bus took a 225 mile trip in 6 hours. the speed was 40 mph for the first part of the trip, and 25 mph for the return trip. how many hours were traveled at each speed
Answer provided by our tutors
Lets assume the speed was 40 mph in x hour and the speed was 25 mph in y hour
.
So x+y=6
40x+25y=225
Solve these equation x=5 and y=1
Then the speed was 40 mph in 5 hour and the speed was 25 mph in 1 hour
