It'll take 25 hours to get to the auto shop
Step-by-step explanation:
Given
Distance = 5 miles
Speed =1056 feet per hour
Required
How long will it take to the auto shop
This can be solved using Speed's formula;

Substitute values for Speed and Distance

1 mile = 5280 feet;
So:


Cross Multiply

Divide both sides by 1056ft



<em>Hence, it'll take 25 hours to get to the auto shop</em>
Step-by-step explanation:
There are 10 + 20 = 30 total students in the class.
Total marks for the class = 60 * 30 = 1800.
Total marks for the girls = 54 * 20 = 1080.
=> Total marks for the boys = 1800 - 1080 = 720.
Mean mark for the boys = 720 / 10 = 72.
