Answer:
It would take 6 hours for you to travel 72 miles.
Step-by-step explanation:
This question can be solved by a simple rule of three.
We have that:
Each hour, you ride 12 miles.
How many hours will take for you to travel 72 miles?
So:
1 hour - 12 miles
x hours - 72 miles
12x = 72
x = 72/12
x = 6
It would take 6 hours for you to travel 72 miles.
Answer:29
so the mini triangle in the corner is a mini model of the entire triangle, all you have to do is take the width or bottom number and find the factor in which it is smaller, then take the height of the smaller triangle and add the factor in which it increases to it. so the factor goes up by 31 1/2--9=22 1/2 and adding the factor in which it increases to the height is 22 1/2+6 1/2=29 because 2 halfs make a whole.
