First change this to an improper fraction so it is easier to work with. Multiply the whole number by the denominator and then add the numerator to it:
7/3
The answer is 7/3 x 60 sec/min x 60 min/hour = 25,200/3. Then divide 25200 by 3:
25,200/3 = 8400 miles per hour

.........................= 3600 x (7/3)= 8400 miles/hour
