Answer 1

8 phone calls

Explanation:

Eduardo spent 4 minutes on the phone while routing 2 phone calls. In all, how many phone calls does Eduardo have to route to spend a total of 16 minutes on the phone? Solve using unit rates.

From the above question:

4 minutes = 2 phone calls

16 minutes = x

Cross Multiply

4 minutes × x = 16 minutes × 2 phone calls

x = 16 minutes × 2 phone calls/4 minutes

x = 8 phone calls

Therefore,

Eduardo has to route 8 phone calls to spend a total of 16 minutes on the phone
