A boy hops on his bike and rides 135 meters in 20 seconds. What is his average speed?
6.75 m/s
To find the average speed, you can use the formula:
Average Speed = Total Distance / Total Time
In this case, the given total distance is 135 meters and the given total time is 20 seconds. So, we can substitute these values into the formula:
Average Speed = 135 meters / 20 seconds
Now, divide the total distance by the total time to get the average speed:
Average Speed = 6.75 meters/second
Therefore, the boy's average speed is 6.75 meters per second.
