You can notice that 14 is 7 time 2, so the answer is 15*2=30. Also, you can use cross multiplication to find your answer.
62,3756 is the number of feet he ran. Divided by 5280, that is 12.075 miles in 70 minutes. Divide 12.075 by 70 to get the miles per minute(0.1725). Then, multiply by 60 to get 10.35, the answer. Therefore, Sam ran at 10.35 miles per hour.

10 years, so
Interest on the Loan:
Total amount:
The borrower will pay back $4,136.
1,225*1.578=1993.05*10^-4
since the decimal place is moved 3 to the left
1.99305*10^-4*10^-3
1.99305*10^-7
