ANSWER:
The rate of the jet in still air is 802 mph and the speed of the jetstream is 40 mph
Explanation:
Given:
Let
x = the jet rate at no wind (in mph)
y = the rate of the wind.
Therefore:
We solve the system by means of the matching method, equating both equations like this:
The rate of the jet in still air is 802 mph and the speed of the jetstream is 40 mph.
