If a man reduces his speed by \(\frac{8}{13}\), he takes 10 hours more in walking a certain distance . The time to cover the distance with his normal speed is ?

16 hours

Reduces his speed by \(\frac{8}{13}\)

  Ratio           Initial   :     New 

 Speed             13     :      8

 Time               8      :      13

According to question ,  5R = 10 hours 

1R = 2 hours

Time at normal speed = 8R = 16 hours
