1) 1hour 10minutes =

hours,
50 minutes =

hours
2) speed of plane against the wind =

3) speed of plane on the the wind =

4) (336-240):2=48miles/hours - speed of wind
5)336-48=288miles/hours - plane's speed <span>in still air
Answer: speed of wind is 48 miles/hours, speed of </span>plane in still air is 288 miles/hours
158+ 148+ 32 + x = 360
