Question

Charise can pick 1/3 pound of berries in 15 minutes.

How many pounds of berries can she pick in 4 hours at the same unit rate?

Answer 1

Explanation:

To convert minutes to hours, we divide by 60, since there are 60 minutes in an hour.

So 4 hours is equal to 4 * 60 = 240 minutes

Charise can pick 1/3 pound of berries in 15 minutes. This is her unit rate. To find out how many pounds of berries she can pick in 4 hours, we need to multiply this unit rate by the number of 15-minute intervals in 4 hours.

240 minutes / 15 minutes = 16 (four-hour intervals)

So the amount of berries Charise can pick in 4 hours is:

1/3 pound/15 minutes * 240 minutes = (1/3) * 16 = 16/3 = 5.333 pounds of berries.

Answer 2

• 5 1/3 pounds of berries

----------------------------------

Charise can pick 1/3 pound of berries in 15 minutes.

There are 4 of 15 minutes in an hour and we need to calculate it for 4 hours.

• 4*4 = 16 of 15 minutes

She picked:

• 1/3*16 =
• 16/3 =
• 5 1/3 pounds of berries
