if one person completed 24 units in 4 minutes how many units will one person complete in one hour

Question

if one person completed 24 units in 4 minutes how many units will one person complete in one hour

Answer 1

The unit rate of "24 units in 4 minutes" is (24 units)/(4 minutes) is 6 units per minute.

 

There are 60 minutes per hour [(60 min)/(1 hr) = 1, use the multiplicative identity to change the units].

 

The rate is (6 units/min)*(60 min/hr) = 360 units/hr, or 360 units per hour.

Answer 2

60 / 4 = 15 (60 minutes in an hour. Divide by 4 (which is the incremental amount given), and that gives us 15 times the person completes the units)

 

15 * 24 = 360 (24 units completed in each increment times 15 increments gives us 360 units total)
