If a man reduces his speed by \(\frac{22}{25}\), he takes 9 hours more in walking a certain distance . The time to cover the distance with his normal speed is ?

66 hours

Reduces his speed by \(\frac{22}{25}\)

Ratio             Initial   :     New 

 Speed             25     :      22

 Time               22     :      25

According to question ,  3R = 9 hours 

1R = 3 hours

Time at normal speed = 25R = 75 hours
