Answer:
- C=31.4cm , A=78.5cm²
- C=50.24mi. A=200.96mi.²
- C=25.12in. A=50.24in.²
- C=37.68Km A=113.04Km²
Step-by-step explanation:

55mph.
you can solve it using the equation distance=speed x time
your total distance is 714, and you have 2 trains, one traveling some speed, x, and one traveling x+8, both traveling for 7 hours.
your equation would look like this
and you can then solve for x, which would be 47. this is the speed of the slower train, but 47+8=55 with give you the speed of the faster train.
