Two cars traveled equal distances in different amounts of time. car a traveled the distance in 2.4 h, and car b traveled the distance in 4 h. car b traveled 22 mph faster than car a. how fast did car a travel? (the formula r⋅t=d , where r is the rate of speed, t is the time, and d is the distance can be used.) enter your answer in the box.

Car A traveled at 55 mph.

Step-by-step explanation:

Suppose, the speed of Car A is   mph.

As Car B traveled 22 mph faster than Car A , so the speed of Car B will be:

Given that, Car A traveled the distance in 2.4 hours and Car B traveled the distance in 4 hours.

As,  

So, the distance traveled by Car A miles

and the distance traveled by Car B miles

Given that, two cars traveled equal distances. So, the equation will be......

Thus, the speed of Car A will be -33 mph.

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
