A car travelling at 70 miles per hour travelled one hour longer than a truck travelling at 60 miles per hour. If the car and truck travelled a total of 330 miles, for how many hours did the car and truck travel all together?
***
let x=travel time of truck
x+1=travel time of car
distance=travel time*speed
..
60x+70(x+1)=330
60x+70x+70=330
130x=260
x=2
x+1=3
Hours car and truck traveled all together=5
