Calculate the average speed (in km/h)of Larry, who runs to the store 3.6 kilometers away in 40 minutes.
Speed = d/t = 3.6km/(40/60)h
.0015 km/h
To calculate the average speed, we need to know the formula for speed. Speed is defined as the distance traveled divided by the time taken. In this case, our distance is 3.6 kilometers and the time taken is 40 minutes.
First, we need to convert the time from minutes to hours, since speed is typically measured in kilometers per hour. There are 60 minutes in an hour, so to convert minutes to hours, we divide the number of minutes by 60.
40 minutes ÷ 60 minutes/hour = 0.67 hours
Now we have our distance of 3.6 kilometers and our time of 0.67 hours. To find the average speed, we divide the distance by the time:
Average speed = Distance ÷ Time
Average speed = 3.6 kilometers ÷ 0.67 hours
Using a calculator, we can find the answer:
Average speed ≈ 5.37 km/h
Therefore, the average speed of Larry running to the store is approximately 5.37 km/h.
