Dr. walker just started an experiment. she will collect data for 9 days. how many hours is this?

216 hours

Step-by-step explanation: To convert 9 days into hours, we first start with the conversion factor for hours and days.

Conversion factor ⇒ 1 day = 24 hours

Next, notice that we are going from a larger unit "days" to a smaller unit "hours" and when we go from a larger unit to a smaller unit we multiply by the conversion factor.

So we multiply 9 by the conversion factor which is 24.

9 × 24 = 216

Therefore, Dr. Walker will collect her data for 216 hours.
