If a man reduces his speed by \(\frac{13}{17}\), he takes 8 hours more in walking a certain distance . The time to cover the distance with his normal speed is ?

26 hours

Reduces his speed bt \(\frac{13}{17}\)

Ratio             Initial   :     New 

 Speed             17     :      13

 Time               13     :      17

According to question ,  4R = 8 hours 

1R = 2 hours

Time at normal speed = 13R = 26 hours
