Two airplanes leave at the same time from airports that are 880 miles apart from each other. If one plane travels 126 miles per hour faster than the other and they pass each other in 2 hours, how fast is each plane traveling?

解答

解答

first plan e^{'} s speed : 283

second plan e^{'} s speed : 157

求解步骤

Translate the problem into an equation:

x \cdot 2 + (x - 126) \cdot 2 = 880

求解

x, x \cdot 2 + (x - 126) \cdot 2 = 880 : x = 283

找到 speed

first plan e^{'} s speed : 283

second plan e^{'} s speed : 157
