A boy hops on his bike and rides 135 meters in 20 seconds. What is his average speed?
Here is the definition:
Avg. Speed = (distance)/(time)
You do the calculation.
post it.
To find the average speed of the boy, you need to divide the total distance traveled by the total time taken. In this case, the boy rode a distance of 135 meters in 20 seconds.
Average Speed = Total Distance / Total Time
So, the average speed can be calculated as:
Average Speed = 135 meters / 20 seconds
To simplify this calculation, divide the numerator and denominator by the common factor of 5:
Average Speed = (135 meters / 5) / (20 seconds / 5)
= 27 meters / 4 seconds
Therefore, the average speed of the boy is 27 meters per 4 seconds.
