Two men walk at rates of 6 miles per hour and 10 miles per hour respectively. They started from the same place walking in opposi
dem82 [27]

Answer:

12.5 hours.

Step-by-step explanation:

First man walks in one hour =  6 miles

Second man walks in one hour =  10 miles

Since they are walking in opposite direction so distance between them after 1 hour   =  6 + 10 = 16 miles

Since after one hour they are 16 miles apart from each other

Therefore, they will be 200 miles apart  from their starting point

= 200 ÷ 16 = 12.5 hours.

After 12.5 hours they would be 200 miles apart.
