Question

Can someone explain it to me please​

Answer 1

4) 23.3

5.1) 22.2

5.2) 0.045

Explanation:

4) minutes per worksheet = minutes/ worksheets

2 hours and 20 minutes = 120 minutes and 20 minutes = 140 minutes.

6 worksheets in total so:

140/6= 23.333.. (23.3 bar)

5) same thing

total km per total liter = total km divided by total liter= km/l

200/9= 22.22.. ( 22.2 bar)

5.2) same thing but opposite

total liter of total km= l/km = 9/200 = 0.045
