sasha can mow 3/8 of an acre of grass in 45 min. how many acres of grass does sasha mow per hour?

OK.....think about this

The first 15 minutes she mows 1/8 of an acre

The next 15 minutes, she mows 1/8 of an acre again  .....that's 1/8 + 1/8  = 2/8 = 1/4 acres in 30 min

So.....since she mows 1/4 of an acre in 30 minutes....in one hour, she must be able to do twice as much......does that help??

Note that she mows 1/8 of an acre every 15 minutes

And there are 4 15 minute periods in an hour.....

Can you take it from there??

i wanna know how to do the problem, that is all.

yes  thank you
