Erica can run 1/6​ start fraction, 1, divided by, 6, end fraction of a mile in a minute. Her school is \dfrac23 ​3 ​ ​2 ​​ start fraction, 2, divided by, 3, end fraction of a mile away from her home. At this speed, how long would it take Erica to run home from school?

Respuesta :

She runs 1/6 mile per minute.

School is 2/3 of a mile away from her home.

Rewrite 2/3 to have the same denominator as 1/6:

2/3 = 4/6

Divide distance by speed:

4/6 / 1/6 = 4/6 x 6/1 = 24/6 = 4

It will take her 4 minutes.
