To cover 50 miles the man needs (time) = (distance)/(rate) = 50/10 = 5 hours = 300 minutes. He will also rest 4 times (after 10, 20, 30 and 40 miles), so total resting time = 4*6 = 24 minutes.

Total time = 300 + 24 = 324 minutes.

walking at the rate of 10mph, man will take 1 hour (60 minutes) to complete the 10 miles. since he rests for 6 minutes every 10 mile i.e. after every hour. therefore total time that he will took to travel 40 miles will be (60 +6 (rest))*4=264. and the remaining 10 miles we will complete in 60 minutes. therefore total time taken = 264+60=324

doesn't he rest 5 times? because 40 to 50th is 10 miles as well - so rest time is 30 minutes and not 24 minutes =>330 and not 324?any suggestions

10th mile
20th mile
30th mile
40th mile
50th mile



Consider at 0 miles...

After every 10 miles he takes rest for 6 minutes...we need to find time taken to cover 50 miles

So he will be resting at a,b,c and d...and after that he covers 50 miles...so whether he takes rest or not is immaterial because we need time to find time to cover 50 miles

Ans is D..

Rate x Time = Distance
10 mph x 1 Hour = 10 miles

So to walk 50 miles he should take 5 Hour , 50/10=5 hour
But after every ten miles he rests for 6 minutes.
The time he reaches the destination he will rest for 4 times ,not 5 times because he already reached his destination.

So 6 mins x 4 = 24 mins

So combined time = 5 hours + 24 mins = 324 minutes.

To cover 50 miles the man needs (time) = (distance)/(rate) = 50/10 = 5 hours = 300 minutes. He will also rest 4 times (after 10, 20, 30 and 40 miles), so total resting time = 4*6 = 24 minutes.

Total time = 300 + 24 = 324 minutes.

Answer = D = 324

Time taken for first 40 miles \(= (60+6)*\frac{40}{10} = 264\)

Time taken for last 10 miles \(= 60*\frac{10}{10} = 60\)

Total time = 264 + 60 = 324
