Question

Roni and Allie are mowing the grass at the soccer field. Roni has a riding lawn mower and can mow the field in 30 minutes. Allie is pushing a lawn mower and can mow the field in 75 minutes.

If Roni and Allie work together to mow the field, what part of the field would Roni mow?

Answer 1

If Roni and Allie are working together, Roni will mow .71 of the field.

in a chart, Roni's rate would be 1/30 and Annie's rate would be 1/75.

both of thier times would be x

and the part of field mowed would be 1/30x for Roni and 1/75x for Annie.

the answer is .71

hope this helps :)
