Two trains leave Raleigh at the same time, one traveling north, the other south. The first train travels at 50 miles per hour and second at 60 miles per hour. In how many hours will the trains be 275 miles apart?

let the time be t hours
distance going north = 50t
distance going south = 60t
solve 50t + 60t = 275
let me know what you get.

You are meeting a friend who lives 285 miles away. You both leave at the same time and head directly toward each other. You travel at a speed 10 mph faster than your friend. You finally meet after each traveling for 5 hours. What was your speed, in mph, to the nearest tenth?
