nikitadnepr [17]

Answer:

Part 1) The length of the new rectangle is 87.5\ ft

Part 2) The area of the new rectangle is 4,375\ ft^{2}

Step-by-step explanation:

we know that

If two rectangles are similar, then the ratio of its corresponding sides is proportional

step 1

Find the length of the new rectangle

Let

L-----> the length of the new rectangle

\frac{50}{20}=\frac{L}{35}\\ \\ L=50*35/20\\ \\L=87.5\ ft

step 2

Find the area of the new rectangle

we know that

The area of the rectangle is

A=LW

we have

L=87.5\ ft

W=50\ ft

substitute

A=(87.5)(50)=4,375\ ft^{2}

One car travel 56 miles per hour and another travels 31 miles per hour. If they start from the same place at the same time and t
Vitek1552 [10]

After 3 hours, the faster car will be 75 miles ahead of the slower car.

Step-by-step explanation:

Given,

Speed of first car = 56 miles per hour

Speed of second car = 31 miles per hour

Let,

x be the number of hours.

Distance covered by first car = Speed * time = 56x

Distance covered by second car = 31x

According to given statement;

Difference between distance covered by both cars = 75 miles

Distance of faster car - Distance of slower car = 75 miles

56x-31x=75\\25x=75

Dividing both sides by 25

\frac{25x}{25}=\frac{75}{25}\\x=3

After 3 hours, the faster car will be 75 miles ahead of the slower car.
