Two cars are leaving at the same time from two different provinces which are 150 km apart. If car A travels at 5 kph faster than car B, find their rates if they meet after two hours.
***
letx=rate of car B
x+5=rate of car A
travel time*rate=distance
..
2x+2(x+5)=150
2x+2x+10=150
4x+10=150
4x=140
x=140/4=35
x+5=40
..
rate of car B=35 kph
rate of car A=40 kph
