Deandra is doing her math homework. out of 24 problems total, she completed the first 12 problems in 1 hour and the last 12 problems in 3 hours. what is the unit rate for all 24 problems? 4 problems per hour 6 problems per hour 8 problems per hour 12 problems per hour

Unit rate for all 24 problems is:

6 problems per hour

Step-by-step explanation:

Out of 24 problems total, Deandra completed the first 12 problems in 1 hour and the last 12 problems in 3 hours.

Total time taken by Deandra to complete her homework=(3+1) hours

                                                                                              = 4 hours

i.e. she did 24 problems in 4 hours

i.e. she did 24/4 problems in 1 hour

i.e. she did 6 problems in 1 hour

Hence, unit rate for all 24 problems is:

6 problems per hour

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

yes
