two cars are 310 miles apart and are traveling towards each other. one car travles 8 mph faster than the other car. tha cars meet in 2.5 hours. find the speed of each car

Answer 1

distance = speed times time

d = st

310 = s(2.5) + (s+8)(2.5) = 2.5s + 2.5s + 20

5s = 290

s = 58 mph for the slower car

s+8 = 66 mph for the faster car

58+66 = 124

2.5 times 124 = 310
