The car is speeding at a rate of 33.3mph

<h3>Speed and distance of an object</h3>

If a certain car going 60 mph can stop in 180 ft, then we can express this as:

  • 60mph = 180ft

To determine the speed for a car traveling at 100ft, we will have:

  • x = 100ft

Take the ratio of the expression

60/x = 180/100
180x = 6000

x = 33.3mph

Hence the car is speeding at a rate of 33.3mph

A painting is 2 in tall and 3 in wide. If it is enlarged to a width of 15 in then how tall will it be?
vekshin1

Answer:

10 in

Step-by-step explanation:

Old proportions:

2 x 3

New proportions

h x 15

Assuming the painting has been increased by a constant scale factor.

Where x is the unknown scale factor, and h is the height after it has been enlarged.

3 * x = 15\\2 * x = h

Rearrange second equation:

3 * x = 15\\x =\frac{h}{2}

Substitute:

3*\frac{h}{2} =15\\\frac{h}{2}=5\\h=10
