Quantitative Aptitude ( CCS) Time & distance

A man can reach a certain place in 30 hours. If he reduces his speed by 1/15th, he goes 10 km less in that time. His speed is ?

4 km/hr

5 km/hr

5 1/2 km/hr

6 km/hr

Ratio of speed = 15 : 14
Ratio of time = 14 : 15
14 = 28 hrs
15 = 30 hrs
So, in 2 hrs it travels 10 kms
Speed = 10/2 = 5 km/hr

Hence, option 2 is the correct answer.
