Manny walks for 30 min at a speed of 5 km/h. How far does Manny walk? A. 2.5 km B. 7.5 km C. 75 km D. 150 km

OpenStudy (anonymous):

150 km

OpenStudy (orange_):

multiply 30 min by 2.5

OpenStudy (orange_):

Since 30 min is half of a hour, divide 5 by 2

OpenStudy (orange_):

So C

OpenStudy (anonymous):

multiply 30 by 60 and divide by 2

OpenStudy (anonymous):

it's D

OpenStudy (juicyme_love):

oh thanks james <3 don't be mad at him 4 giving derect answer im in a rush anyways

OpenStudy (orange_):

It is C!!

OpenStudy (anonymous):

How?

OpenStudy (juicyme_love):

C or D and simply say how?

OpenStudy (anonymous):

If 300 km is in 60 minutes and you split it in half its 150!

OpenStudy (orange_):

Because, look, it is 5km/h h = HOUR. 30 min is 1/2 of an hour, so you can multiply 5 by 30 and divide by 2.

OpenStudy (anonymous):

If you multiply 60 by 5 you get 300 and just cut it in half after that

OpenStudy (anonymous):

It's 150

OpenStudy (orange_):

I looked it up, 75.

OpenStudy (juicyme_love):

75 than..

OpenStudy (juicyme_love):

right

OpenStudy (anonymous):

I'm 1005% certain it's 150

OpenStudy (jahernandez):

stop confusing her and tell her the right answer

OpenStudy (juicyme_love):

:( oh my..

OpenStudy (anonymous):

It's 150!!

OpenStudy (juicyme_love):

fine than.

OpenStudy (anonymous):

just do 30 * 5 you don't need to divide it

OpenStudy (orange_):

YESSS, you do.

OpenStudy (anonymous):

were both wrong

OpenStudy (anonymous):

it's 2.5 because she goes 5km in an hour and she only went for half that
