The time required for a trip of a certain distance in a car varies indirectly as the rate the car travels. A trip took 18 hours traveling at 50 miles per hour. How long would this trip take if the car was traveling at 75 miles per hour?
If you multiply 18 by 50, you would get how long the trip is, which is 900 miles. Then, divide 900 by 75, you would then get the answer of 12. The trip would take 12 hours at 75 mph.
