Answer:
Rate of the plane in still air: 940km/h
Rate of the wind: 1440km/h
Step-by-step explanation:
We want to find the rates of travel in km/h, so we will put kilometers over hours.
Rate of plane against wind: 3760km/4hrs
3760/4 = 940
The rate of the plane against the wind is 940km/h
Rate of plane with wind: 11,520km/8hrs
11,520/8 = 1440
The rate of the plane with the wind is 1440km/h
Distribute -1/5 into the parentheses. Then you have -1/5x-25=7. Add 25 to both sides to get the equation-1/5x=32. Then divide both sides by -1/5 to get your answer.
