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.
Let X = speed of one boat and X + 4 = the other.
.7X + .7(X + 4) = 9.8
I hope this helps. Thanks for asking.
