Respuesta :
The unit rate at which Darrell walks is 1.5 meters per second.
Unit rate is defined as per unit time. Unit rate can be anything from speed, acceleration or any other measurement.
The quantity that is achieved in a single unit of time is called the unit rate.
The unit rate is calculated by dividing the total amount by total time that is taken to complete the total amount.
Here Darrell walks 90 meters in 60 seconds.
The unit time to be considered here is 1 second.
so Darrell walks a certain amount of distance in 60 seconds.
Therefore the unit rate in which he walks = total distance covered ÷ total time taken
∴ unit rate = 90 ÷ 60 meters per second = 1.5 meters per second.
Disclaimer : The complete question is : In 60 seconds, Darrell walks 90 meters. Find the unit rate at which Darrell walks.
