Two cars travel in opposite direction for 3hrs.
one car is 3 miles per hour faster than the other
so one is x miles/hr other is x+3 miles/hr
so in 1 hr they move x+x+3 miles & in 3 hrs 3(2x+3)
after 3hrs they are297 miles apart.
so 3(2x+3)=297
or 2x+3=99
or x=48
so so one is 48 miles/hr other is 51 miles/hr
