Question

A car travels at 65 miles per hour. Going through construction, it travels at 3/5 this speed. Write this fraction as a decimal and find the speed.

Answer 1

3/5 = 60/100 = 0.6

65
x 60
= 00
3900

3900 / 100 = 39.

While going through construction, the car travels at 39mph.

Answer 2

Speed = 39. 0 miles per hour.

Explanation:

Given : A car travels at 65 miles per hour. Going through construction, it travels at 3/5 this speed.

To find : Write this fraction as a decimal and find the speed.

Solution : We have given

A car travels in 1 hour = 65 miles .

Speed =
`(distance)/(time)`.

Speed =
`(65)/(1)`

Speed = 65 miles per hour .

According to question :

It travel
`(3)/(5)` of the speed.

To convert fraction in to decimal .

`(3)/(5)` = 0.6

So, it travel 0.6 of speed .

Speed = 0.6 * 65 .

Speed = 39. 0 miles per hour.

Therefore, Speed = 39. 0 miles per hour.
