Question

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?

A 4(1/2) days Correct Answer Incorrect Answer
B 11 days Correct Answer Incorrect Answer
C 15(1/2) days Correct Answer Incorrect Answer
D 22 days Correct Answer Incorrect Answer
E None of these Correct Answer Incorrect Answer

Solution

Working hours per day = 24 – 8 = 16 hours Total working hours = 16 ×11 = 176 hours Distance is doubled and speed too. (Both cancel each other) New working hours (per day) = 24 – 16 = 8 hours ∴ Required Time = 176/8 = 22 days
