Question

In 60

seconds, Darrell walks 90
meters.

Select the two answers that describe the unit rate at which he walks.

Answer 1

Darrell walks at a unit rate of 1.5 meters per second or 90 meters per minute, calculated by dividing the distance by the time.

Step-by-step explanation:

In 60 seconds, Darrell walks 90 meters. To describe the unit rate at which Darrell walks, we calculate the speed by dividing the distance by the time. This gives us a unit rate of:

Speed = Distance / Time = 90 meters / 60 seconds = 1.5 meters per second.

The two descriptions of the unit rate at which he walks could be:

• 1.5 meters per second
• 90 meters per minute (since there are 60 seconds in a minute)
