Answer:
The correct answer is 2222.2 cm/s.
Explanation:
The expression for the distance- time relation is as follows;
D=st
Here, D is the distance, s is the speed and t is the time.
It is given in the problem that a car travels 4 km in 3 minutes.
1 km= 100000 cm
1 min= 60 s
Calculate the speed of car in cm/s.
Put D= 4 km and t= 3 min in the above expression.
(4 km)=s(3 min)
s= 2222.2 cm/s
Therefore, the speed of the car is 2222.2 cm/s.
