6) 20 minutes is 1/3 of an hour. To find out how many T-shirts per hour, we multiply how many can be produced in 20 minutes by 3.
5 T-shirts X 3 =
15 T-shirts per hour.
7) From Jefferson to Paxten overall, it's 300 miles. Since we're determining miles per hour, we divide 300 by 5 to find out how fast he was travelling.
300 / 5 = 60 MPH
8) This problem explains a fraction, we just have to find the corresponding fraction with a missing denominator.
360 / 12
400 / ?
360 / 400 = 9 / 10
Multiplying the reciprocal by 12 will give us the answer.
(10 / 9) X 12 = 13 Hours and 20 Minutes.
Hope this helps!
