6-88.

A train traveled 90 miles in 1.5 hours. At the same rate how long will it take the train to travel 330 miles. Homework Help ✎

Use proportions to solve and show your work with units.

Solve using

*d*=*rt*.Did you get the same solution?

Since 90 miles is the distance (*d*) and 1.5 hours is the time (*t*), substitute in and solve for the rate (*r*).

Yes, both methods resulted in an answer of 5.5 hours to travel the 330 miles.
