A car is driving at 64.2 miles per hour. How many seconds does it take to drive 14.8 miles?

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
