It takes eight hours for a 600 km journey, if 120 km is done by train and the rest by car. It takes 20 minutes more, if 200 km is done by train and the rest by car. The ratio of the speed of the train to that of the cars is:

Question

anonymous · Answer

the question is worded very badly

anonymous · Answer

so distance = speed x time

anonymous · Answer

time = distance / speed

anonymous · Answer

let the train speed be x, and the car speed be y

anonymous · Answer

The first sentence tells us that (120/x) +(480/y) = 8 { note: all values are in km and hours , therefore when we solve the equations the units of x and y will be km /hr ( not that it matters because they want the ratio

anonymous · Answer

the second sentence tells us that (200 / x ) + 400/ y = 8 1/3 ( note 1/3rd of an hour = 20mintues

anonymous · Answer

then solve them
