Posted by on .

Two sailboats are 9.8 miles apart and sailing toward each other. The larger boat sails 4 miles per hour faster than the smaller boat. The two boats pass each other after 0.7 hour. Find the speed of each boat.

I cannot figure out for the life of me how to set this one up. I already have the answer in the back, but it's just getting this set up is the problem.

Thanks!

  • Algebra 2 - ,

    Let X = speed of one boat and X + 4 = the other.

    .7X + .7(X + 4) = 9.8

    I hope this helps. Thanks for asking.
