Based on the Roni using a lawn mower and Allie pushing one, Roni would be able to mow 0.71 of the field.
<h3>How much of the field would Roni mow?</h3>
Assume that the part of the field that Roni would mow is x.
The relevant equation would be:
x/30 + x/75 = 1
5x/150 + 2x/150 = 1
7x / 150 = 1
x = 21.43
In 30 minutes, Roni would have mowed:
= 21.43 / 30
= 0.71
Full question is:
