Problema Solution
if a plane can travel 480 miles per hour with the wind and 380 miles per hour against the wind, find the speed of the plane with and without a wind and the speed of the wind
Answer provided by our tutors
let 'v' represent the speed of the wind
we average the two speeds to find the speed of the plane without the wind
(480+380)/2 = 430
the speed with the wind is '430+v':
480 = 430+v
v = 50
the speed of the plane without the wind is 430 mph, the speed of the wind is 50 mph
