Question

Two cars leave an intersection at the same time. Car A travels at a constant speed of 60 mph east, while Car B travels at a constant speed of 45 mph west. What is the velocity of Car A relative to Car B?

a) 105 mph east
b) 15 mph west
c) 105 mph west
d) 15 mph east

Answer 1

The velocity of Car A relative to Car B is 105 mph east.

Step-by-step explanation:

The velocity of Car A relative to Car B can be calculated by subtracting the velocity of Car B from the velocity of Car A. Since Car A is traveling east at a speed of 60 mph and Car B is traveling west at a speed of 45 mph, the velocity of Car A relative to Car B is 60 mph - (-45 mph) = 105 mph east.
