This one actually made me think. I like your teacher.
2h 30min (2.5)×30mph=75m
1h 30min (1.5)x50mph=75m
1 hour longer when driving to Arkansas
______________________________
11h 12min (11.2)×300mph=3360m
4h 48min (4.8)×700mph=3360m

Given:
The ratio of the measures of the sides of a triangle is 3:4:5.
Its perimeter is 48 inches.
To find:
The scale factor as a decimal, and the measure of each side of the triangle.
Solution:
Let x be the scale factor. Then the measures of sides of the triangle are 3x, 4x and 5x.
The perimeter of the triangle is 48 inches. It means the sum of all sides of the triangle is 48 inches.


Divide both sides by 12.


Now, the measures of sides are:


Similarly,


And,


Therefore, the scale factor is 4 and the measures of sides are 12, 16 and 20.
Answer:
12
Step-by-step explanation:
u have to mutypl and div it up sum and k/=+56+8=90/h=+5689-097/p=11+y=1+11=12
