Question 8

To cover a distance of 234 km in 1.6 hours what should be the average speed of the car in meters/second?

Solution

The car covers 234 km in 1.6 hours

Speed of car (in km/h) = $$\frac{234}{1.6} = 146.25$$ km/hr

=> Speed of car (in m/s) = $$146.25 \times \frac{5}{18}$$

= $$8.125 \times 5 = 40.625$$ m/s

=> Ans - (A)
