Answer 2

Brielle will run the marathon faster. Brielle will take 104.8 minutes to finish the race and  Joshua will take 157.2 minutes to finish the race.

What is division?

The division is simply dividing a number by another number.

Given in the question the marathon race is of 13.1 miles long.

Brielle takes 10 minutes to cover 1.25 miles.

So to cover 1 mile he will take = 10/1.25=  8 minutes

So to finish the marathon race i.e. to cover 13.1 miles he will take the time= 8*13.1= 104.8 minutes.

Joshua takes 18 minutes to cover 1.5 miles.

So to cover 1 mile he will take = 18/1.5=  12 minutes

So to finish the marathon race i.e. to cover 13.1 miles he will take the time= 12*13.1= 157.2 minutes.

So from above, it is clear that Joshua is taking more time than Brielle to finish the race.

Brielle will run the marathon faster as he takes less time to finish.

Therefore Brielle will run the marathon faster. Brielle will take 104.8 minutes to finish the race and  Joshua will take 157.2 minutes to finish the race.
