Question

A man walks at 3 mph for half way and doubles his speed for the other half.If total time is 5 hrs find total dist

Answer 1

Answer:

22.5 miles

Step-by-step explanation:

Total time the man walked = 5 hrs

Speed of the man for first half i.e. first 2.5 hours = 3 mph

So distance traveled in first half = 2.5 x 3 = 7.5 miles

The man doubles his speed for the second half. So speed of the man for the second half i.e., second 2.5 hours = 6 mph

So distance traveled in first half = 2.5 x 6 = 15 miles

Total distance traveled = distance traveled in first half + distance traveled in second half

⇒ 7.5 + 15 = 22.5 miles

∴ Total distance traveled by the man in 5 hours is 22.5 miles
