If a plane can travel 470 mph with the wind and 430 mph against the wind , find the speed of the plane without a wind and speed of the wind.

Thank you for the opportunity to help you with your question!

Let speed of plane be x. Let speed of wind be y. x + y = 470 --- (1) x - y = 430 --- (2) From (2), we have: y = x - 430 --- (3) Substituting (3) into (1), we will get: x + x - 430= 470 2x = 900 x = 450 Substituting x = 450 into (3), we will get: y = 450 - 430 y = 20 Hence, speed of plane is 450 mph, while speed of wind is 20 mph.
