Answer:
Average speed of the car is 36.36 miles per hour
Explanation:
It is given that,
Total distance traveled by the car, d = 200 miles
Total time taken, t = 5.5 hours
In this case, we have to find the average speed of the car. Average speed of the car is defined as the total distance divided by total time taken. Mathematically, it can be written as :
s = 36.36 miles per hour
Hence, the average speed of the car is 36.36 miles per hour. \
