Answer:
Speed of car is 78 mph which travels the distance in 6 seconds.
Step-by-step explanation:
Given:
Speed of the car R = 52 mph
Time t = 9 seconds
We need to find the speed of a car that travels the given distance in 6 seconds.
Now first we will find the distance traveled by the car in 9 seconds.
Distance can be calculated by multiplying speed and time.
Distance = 
Hence Total distance travel by car is 468 miles.
Now we will find the speed of a car that travels the given distance in 6 seconds.
Speed can be calculate by dividing Distance by time.
Hence;
Speed = 
Hence Speed of car is 78 mph which travels the distance in 6 seconds.
Answer:
