how do I solve this and show the work:

a motorboat went upstream at 15 miles per hour and returned downstream at 20 miles per hour. How far did the boat travel one way if the round trip took 3.5 hours?

  • algebra -

    since time = distance/speed, add up the total time:

    d/15 + d/20 = 3.5
    d = 30
