Question 2

# A car runs at the speed of 40 when not serviced and runs at 65 kmph when serviced. After servicing the car covers a certain distance in 5 hours. How much approximate time will the car take to cover the same distance when not serviced ?

Solution

After servicing, the distance covered by car in 5 hours = 65 * 5 = 325 km

Without servicing, speed of car = 40 kmph

=> Required time = $$\frac{Distance}{Speed}$$

= $$\frac{325}{40}$$ = 8.125 hr

$$\approx$$ 8 hours
