Car a travels 20 mph faster than car b. in the same time that car a travels 252 miles, car b travels 196 miles. find their speeds

A = 70

B = 90

Step-by-step explanation:

We know that Car A travels 20 mph faster than Car B.

Assuming the speed of Car B to be x and the speed of Car A to be x+20, we can write:

Taking the reciprocal of both sides to make x the subject:

---> speed of Car A

Finding the speed of Car B:

Therefore, the speed of Car A = 70 and the speed of Car B = 90.
