Question

Selena rides her bicycle to work. It takes her 15 minutes to go 3 miles. If she continues at the same rate, how long will it take her to go 8 miles?

Answer 1

Since she is going 3 miles per 15 min you basically divide 15 by 3 to find out how many min does it take to get to one mile so you'll get 5 min per mile so 5 times 8 equals 40 in which it takes her 49 minutes

Answer 2

The answer is: " 40 minutes " .

Step-by-step explanation:
___________________________________________

`(15 min)/( 3 mi)` *
`(8 mi)/(1)` ;

=
`(5 min)/( 1 mi)` *
`(8 mi)/(1)` ;

=
`(5 min)/( 1 mi)` *
`(8 mi)/(1)` ;

=
`((5 min)*(8))/(1)` ;

=
`(40 min)/(1)` ;

= 40 min.
