There were 48 peaches in a carton. The average mass of all the peaches was 0.17 kg. What was their total mass?

alexira [117]

Answer:

8.16 Kg

Step-by-step explanation:

average is calculated as

average = $\frac{sum}{count}$

here average = 0.17 and count = 48 , then

0.17 = $\frac{sum}{48}$ ( multiply both sides by 48 )

8.16 = sum

that is total mass = 8.16 Kg
