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?
a. about 0.52 of the field
b. about 0.64 of the field
c. about 0.71 of the field
d. about 0.87 of the field

C. about 0.71 of the field

Step-by-step explanation:

Since,  Roni can mow the field in 30 minutes.

Thus, the work done by Roni in one day = 1/30

And,  Allie can mow the field in 75 minutes.

add both sides by 9

divide both sides by 4

we get

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
