I was taught that problems involving distance, time, and speed can be solved by using the "DiRT" equation. "**Distance** *is* **Rate** times **Time**." Distance = Rate x Time. Rate is the same thing as speed. The question being asked here is not a distance question—it's a question of time—but the formula can be rearranged to solve the problem. The new formula is Time = Distance/Rate.

Time = 14.8 miles/64.2 mph

Time = .23 hours.

The next task is to convert the .23 hours to seconds. (This could be avoided if you first convert the speed from miles per hour to miles per second. Either method will work.) Below is how to convert the hours to minutes.

The following equation will convert the .23 hours to minutes.

0.23 hours = *n *minutes/60 minutes per hour

n = 0.23 hours x 60 minutes per hour

n = 13.8 minutes

13.8 minutes x 60 seconds per minute = 828 seconds
