An object covers a distance of 20 meters in 4 seconds. What is its average speed?

C. 5 m/s — Average speed is defined as the total distance divided by the total time taken. Dividing 20 meters by 4 seconds yields 5 meters per second.

$An object covers a distance of d = 20 m in t = 4 s . What is its average speed?$

A. $2 m/s$
B. $4 m/s$
C. $5 m/s$
D. $8 m/s$

Show correct answer & step-by-step solution

Correct answer: C — $5 m/s$

Solution

Average speed is defined as v_{avg} = distance / time . Thus, v_{avg} = 20 m /4 s = 5 m/s .
