Question 62
The speed of a car is 20 m/s. How much distance (in km) will the car travel in 2.5 hours?
Solution
Here we need the distance in km. So for that, we need to convert the speed which is given in m/s to km/h.
The speed of a car is 20 m/s.
speed of a car = $$20\times\ \frac{3600}{1000}$$ km/h
= $$20\times\ \frac{36}{10}$$ km/h
= 72 km/h
Distance covered by the car in 2.5 hours = $$72\times2.5$$
= 180 km
