Question

Calculate the average speed of an insect that walked 27 centimeters in 9 seconds. *

A 9 cm/s
B 27 cm/s
C 243cm/s
D 3 cm/s

Answer 1

Answer:

D) 3cm/s

Step-by-step explanation:

Speed (or velocity) is calculated with d/t (distance/time). From the multiple-choice options, we know the unit is cm/s, which makes it super convenient.

Now, using the equation and seeing that 27cm is the distance and 9s is the time, 27/9 =3.

Therefore, the answer is D, 3cm/s.

Hope that helps!
