A man can reach a certain place in 30 hours. If he reduces his speed by 1|15 th, he goes 10 km less in that time. Find his speed in km | hr?
Answer: 15 km/h
Explanation
Distance covered in 30 hours = 30x km
New speed = [x−15x]km/hr=1514xkm/hr
Distance covered in 30 hours = 1514x×30= 28x km Given,30x−28x=10km ⇒ x=5km/hr
