Question 886477
Two buses leave from the same station at different times. Bus 1 leaves 2 hours earlier than bus 2. Bus 1 is traveling at 40 miles per hour and bus 2 is traveling at 60 miles per hour. How long will it take bus 2 to catch up to bus 1
***
let x=travel time of bus 2
x+2=travel time of bus 1
distance=speed*travel time (same for both busses)
..
40(x+2)=60x
40x+80=60x
20x=80
x=4
How long will it take bus 2 to catch up to bus 1?  4 hrs
