Hi I need help ASAP
How would I solve these 2 problems with an algebraic equation
1.Two cars leave from the same place at the same time and travel in opposite directions. One car travels at 55 miles per hour and the other at 75 miles per hour. After how many hours will they be 520 miles apart.
2. Jackson rode his bike at 15 miles per hour to get his car. He then drove back at 45 miles per hour. If it took him 8 hours, how far away was his car?
