Question 36925: jim can run 5 miles per hour on level ground on a still day. One windy day, he runs 10 miles with the wind, and in the same amount of time runs 5 miles against the wind. what is the rate of the wind?

Let x be the speed of the wind
10(5-x)=5(5+x)
50-10x=25+5x
15x=25
x=1.67
Hence, the speed of the wind is 1.67 mph.
