Well there is no exact answer
27 miles per hour
1 hour = 60 minutes
27 miles per 60 minutes
27/60 miles per 1 minute
9/20 miles per minute
The equation to calculate how many ways that "r" things can be chosen from a larger set of "n" things is:n! / [r! * (n-r)!] =
12! / (5! * 7!) =
12 * 11 * 10 * 9 * 8 * 7! / (5! * 7!) =12 * 11 * 10 * 9 * 8 / 5 * 4 * 3 * 2 =11 * 9 * 8 =792 ways
