Question

Delia and Beto left for school at the same time.

Delia lives 3/4 mile from school and walks at a pace of
16 minutes per mile. Beto lives 3 1/2 miles from school
and bikes at a pace of 3 minutes per mile. Who will get to
school first?

Answer 1

Beto reaches school first

Explanation:

We are given that Delia lives 3/4 mile from school and walks at a pace of

16 minutes per mile.

So Delia takes
`(3)/(4) * 16 =` 12 minutes to reach school.

While Beto lives 3 1/2 miles from school and bikes at a pace of 3 minutes per mile.

So Beto takes
`(7)/(2) * 3 =` 10.5 minutes to reach school.

Therefore, Beto reaches school first.

Answer 2

Beto will reach school first

Explanation:

Delia lives 3/4 mile from school, and if she walks at 16 minutes per mile, it would take her

3/4 x 16 = 12 minutes to reach school.

Beto lives 3 1/2 (7/2) miles from school, and if she walks 3 minutes a mile, it would take her

7/2 x 3 = 10.5 minutes to reach school

Hope this helps!
