## SAT question.

This is a question taking from the SAT Question Of the Day.

A mechanic can install carburetors in 3 cars every 4 hours. At that rate, how long will it take the mechanic to install carburetors in 5 cars?

How can I do this. By the way tomorrow Is my SAT and I know I will do very poorly.

( Sorry if I posted this in the wrong section I din't know where is it suppose to go"

one way to do this is to find out the rate

rate=3/4per hours

then assume x= how long will it take the mechanic to install carburetors in 5 cars

3x/4=5

x=20/3

so the answer is 6+2/3 hours
