To cover a certain distance with a speed of 60 km/hr, a bike takes 15 hours. If it covers the same distance in 12 hours, what will be its speed?
A65 km/h
B70 km/h
C75 km/h
D80 km/h
Answer:
C. 75 km/h
Read Explanation:
To cover a certain distance with a speed of 60 km/hr, a bike takes 15 hours.
Then the total distance covered will be = speed × time
=60 ×15
=900km
Now the speed needed to travel the same distance in 12 hours will be
Speed = Distance/time
=900 /12
=75kmph
