Question

A laboratory technician can clean 34 pipettes every hour with an automatic washer. How many can he clean in 12 minutes? (Hint: Both time periods must be in the same unit of measurement)

Answer 1

7

Explanation:

you can do a ratio where you have 34 over 60 then cross multiply that ratio with x over 12 and 60x=408 and it equals 6.8 but I am assuming you have to round up.

Answer 2

Answer: 6.8

Explanation:

34 in 60 minutes

In 12 minutes = ( 12/60) * 34
