I drove to the beach at a rate of 40 miles per hour. If I had driven at a rate of 50 miles per hour instead, then I would have arrived 30 minutes later. How many miles did I drive?

Let the distance to the beach==D

Let the time taken to drive to the beach ==T

D /40 == T

D /50 == T - 1/2, solve for D, T

**D==100 miles - distance to the beach**

**T ==5/2 ==2.50 hours - time it takes to drive to the beach**

Note: if you drove at 50 mph, you would get to the beach 30 minutes** EARLIER **and **not LATER !!!**
