You can put this solution on YOUR website! a train and a car are travelling in the same direction towards a bridge.
the car has a head start of 43 metres.
For every 3 metres the car travels, the train travels 5 metres.
How far does the train have to travel to reach the bridge first?
:
Let d = distance traveled by the train
:
Write a time equation, time = dist/speed
: =
cross multiply
5d = 3(d+43)
5d = 3d + 129
5d - 2d = 129
2d = 129
d =
d = 64.5 meters, the car and the train will be at the same point
therefore
At 65 meters is the bridge and the train is first
