Step-by-step explanation:
Speed
Speed is how fast an object moving. It is the distance traveled per unit of time.
To find the speed, we have the formula, s = d / t or speed is equal to distance divided by time.
Let us find the speed of each activity that Jeff did.
Solution:
Biking - d:19 mi, t:2 h
s = d / t
= 19 mi / 2 h
= 8 mi/h
Walking - d:14 mi, t:4 h
s = d / t
= 14 mi / 4 h
= 3.5 mi/h
Running - d:15 mi, t:3 h
s = d / t
= 15 mi / 3 h
= 5 mi/h
Swimming - d:18 mi, t:4 h
s = d / t
= 18 mi / 4 h
= 4.5 mi/h
