A Porsche travelled 1.6 times as fast as the BMW. The difference of speed was 45 km/h. Determine the speed of each car.

A porsche travelled 1.6 times as fast as the BMW. The difference of speed was 45 km/h. Determine the speed of each car.

p=1.6b

p-b=45

What was the final speeds? The equation you used to get them?

In the post of galactus,

p is the speed of the Porshe and b the speed of the BMW.

Solve using simultaneous equations to get the value of p and b, the speeds that you are looking for.
