I drove to the beach at a rate of 40 miles per hour. If I had driven at a rate of 30 miles per hour instead, then I would have arrived $28$ minutes later. How many miles did I drive?

x = distance to beach

x / 40 time at 40 m/hr

x / 30 time at 30 m/hr

x/40 + 28/60 = x/30 solve for 'x' ( 28 minutes is 28/60 hr)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Time => **t **(in minutes)

40t = 30(t + 28)

**t = 84 minutes (min)**

40 miles / 60 min = x miles / 24 min

**x = 16**

You drove **56 miles**
