A cargo plane flew to the maintenance facility and back. It took one hour less time to get there than it did to get back. The speed on the trip there was 220 miles per hour. The speed on the way back was 200 miles per hour. How many hours did the trip there take.
Let the time it took to get to the facility be T

Then time it took to return = T + 1

We then get the following DISTANCE equation: 220T = 200(T + 1)

220T = 200T + 200

220T - 200T = 200

20T = 200

T, or time taken to get to facility =
