Car A passes Car B on the highway. Rlative to car A's movement, Car B is moving at a rate of 9 mph backward. If the speed of Car A is 98 mph, what us the speed of Car B?
B is 9 mph slower than A.
98 - 9 = 89 mph
To find the speed of Car B, we need to take into account its movement relative to Car A.
Given:
- Speed of Car A = 98 mph
- Car B is moving at a rate of 9 mph backward relative to Car A
To determine the speed of Car B, we can subtract the relative speed at which Car B is moving backward from the speed of Car A.
Speed of Car B = Speed of Car A - Relative speed of Car B
Let's calculate it:
Speed of Car B = 98 mph - 9 mph
Speed of Car B = 89 mph
Therefore, the speed of Car B is 89 mph.
