D 315​

Answer 1

To find out how many donuts the shop would sell in 90 minutes, convert the 90 minutes to 1.5 hours and multiply by the rate of 210 donuts per hour to get 315 donuts.

Step-by-step explanation:

The donut shop sold 210 donuts in the first hour, which gives us a unit rate of 210 donuts per hour. To find out how many donuts the shop would sell in 90 minutes, we need to convert the time from minutes to hours and then use the unit rate to find the answer.

First, convert 90 minutes to hours:

90 minutes ÷ 60 minutes/hour = 1.5 hours

Now, multiply the number of hours by the rate of donuts per hour:

1.5 hours × 210 donuts/hour = 315 donuts.

So, the donut shop would sell 315 donuts in 90 minutes.

Answer 2

315 (D)

Step-by-step explanation:

210/60 to get donuts per minute = 3.5 donuts per minute

3.5x90= 315
