Solution:
Step-by-step explanation:
A square is a quadrilateral that has four equal sides and four equal angles that measure 90 degrees (An angle that measures 90 degrees is also known as "Right triangle".
By definition, the perimeter of a square can be calculated by multiplying the length of any of its sides by 4 (because all its sides are congruent, as it was explained before).
In this case, you know that the perimeter of this square is 36 feet.
Then, you can write the following equation to model this situation:
Where "s" is the length of any side of the square.
Then, you need to solve for "s" in order to find its value. Divide both sides of the equation by 4.
You get that it is:
Answer:
23 hours
Step-by-step explanation:
So here we are trying to calculate Time which is Distance divided by Speed
Time =
Firstly, we have to calculate the Speed which is = = 60
This means that the speed is 60 miles per hour or 60 mph.
Then to find the total time we take the Distance and divide it by the Speed:
= 35
So this means that his total trip took 35 hours so lets subtract 12 hours to get how many more hours: 35 - 12 = 23 hours
