QUESTIONS ON TIME, DISTANCE & SPEED (PART-III)

QUERY 21

A car completes its journey of 42 km in 1 hour 40 minutes 48 seconds when it runs at 5/7 of its actual speed. Find the actual speed of the car.

A) 30 km/h
B) 35 km/h
C) 32 km/h
D) 32.5 km/h

MAHA GUPTA
Time taken = 1 h 40 m 48 s = 126/75 hours

Now let the actual speed = x km/h

We know SPEED*TIME = DISTANCE
Therefore, x(5/7)*(126/75) = 42
=> x = 35 km/h (option ‘B’)
