A racing car can complete a 900 m long lap in 15 s. What is the speed of the car?
2 answers:
Answer:
The speed of the car is 60 m/s.
Explanation:
It is given that,
Distance covered by the racing car, d = 900 m
Time taken by the car, t = 15 s
Let v is the speed of the car. The speed of any object is equal to the distance covered divided by total time taken as :
v = 60 m/s
So, the speed of the car is 60 m/s. Hence, this is the required solution.
