Two towns are 165 km apart. A car and a bus start travelling towards each other from their respective towns. The car moves 10 km/h faster than the bus. If they pass each other in 1.5 hours after they began their respective journeys, find the speed of each vehicle.
I'm guessing I have to use the formula:
average speed = (distance travelled)/(time taken)
But I'm not sure...well any help on the above will be appreciated!
two town speed solution
So, for the car, v+10=d/1.5 and for the bus v=(165-d)/1.5
The car travels with velocity 10 km/h faster, so it has velocity v+10 while the bus has velocity v. Then one vehicle travels some distance d and the other travels 165-d since they are driving toward each other and the distance between the town, d+165-d=165km. Solving those two equations, v=50 so v+10=60 so the car travels at 60 and the bus at 50 km/h
