A can walk a certain distance in 11 days when he rests 8 hours a day. How long will he take to walk twice the distance, twice as fast and resting twice as long each day?
Walking hours per day = 24 – 8 = 16 hours Total walking hours = 16 ×11 = 176 hours Distance is doubled and speed too. (Both cancel each other) New walking hours (per day) = 24 – 16 = 8 hours ∴ Required Time = 176/8 = 22 days
