Answer:
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!
