Two buses leave town 1374 kilometers apart at the same time and travel towards each other. One bus travels 17 km/h faster than the other. If they meet in 6 hours, whats the rate of each bus

Answer 1

F=17+S where F= Faster bus speed and S= Slower bus's speed measured in kph

distance = 1374 km

time = 6 hours

1374/6 = 229

S+S+17 = 229

2S = 229-17 = 212

S = 106 kph

F = 123 kph

229(6) = 1374

distance = speed times time

1374 = (F+S)6 = (17+S +S)6 = (17+2S)6 = 102 + 12S

12S = 1374-102 = 1272

S = 1272/12 = 106 kph

F= 106+17 = 123 kph
