Math Help pleaseeeeeeeeeee help 10 points to best

-Ten minutes after Sasha's little brother left home for karate class Sasha saw that he had forgotten his karate uniform and she ran after him. If Sasha runs twice as fast as her little brother how long wil it taker her to reach him

- By what number can each side of 11/20x+ 5/12= 1/60-3/20x be multiplied to clear all fractions?

1. 10 minutes

2. 60

you would multiply by 60
(11/20x+5/12=1/60-3/20x)60
that will cancel the 20(leave a 3 in the numerator)
cancels the 12(leaves a 5 in the numerator)
cancels the 60(leaves a 1 in the numerator)

so then it would look like 33x+25=1-9x
I really hope this helps :)

it'll take her 10 minutes to reach the brother

and 60x/60x

the answer to the second one is 60x/60x

YOU STILL OWE ME PTS FOR THE OTHER ANSWERRRRR ;P
