Answer

25 miles/hour

Explanation

Given that,

A pilot can travel with wind = 416miles

A pilot can travel against wind = 336miles

A pilot can speed without wind = 235miles/hour

let wind speed = v miles/hr

pilot's speed with the wind = 235 + v

pilot's speed against the wind = 235 - v

Time = distance / speed

416 / (235 + v) = 336 / (235 - v)

416 (235 - v) = 336 (235+v)

97760 - 416v = 78960 + 336v

97760 - 78960 = 416v + 336v

18800 = 752v

v = 18800/752

v = 25 miles/hour

wind speed = 25 mph
