Flying with wind, a small plane flew 410 mi in 2 h. Flying against the wind, the plane could fly only 380 mi in the same amount of time. Find the rate if the plane in clam air and the rate of the wind.

197.5 mph.

Step-by-step explanation:

If flying with wind a small plane flew at 410 miles and 380 miles then the next step is to divide both speeds by two. This way you get the mph. So now it is 205 mph and 190 mph. Now we find the average of these two numbers and you get 197.5 mph.

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2
