Question

A slug takes 4.25 minutes to travel 11.2 centimeters. What is the speed of the slug in meters per second?

Answer 1

Answer:

$4.39*10^{-4}\ m/sec$

Step-by-step explanation:

Remember that

$1\ m=100\ cm$

$1\ min=60\ sec$

The speed is equal to divide the distance by the time

Convert the units

$4.25\ min=4.25(60)=255\ sec$

$11.2\ cm=11.2/100=0.112\ m$

so

$0.112/255=0.000439\ m/sec$

$4.39*10^{-4}\ m/sec$

Answer 2

We are to find the average speed in meters per second

The speed in meters per seconds is 0.0004392156862 meter per second

Time taken = 4.25 minutes

Total distance = 11.2 centimeters

• 1 centimeter = 0.01 meters

11.2 centimeter = 0.11 meters

• 1 minutes = 60 seconds

4.26 minutes = 255 seconds

Average speed = Distance / Time

= 0.112 meters / 255 seconds

= 0.0004392156862 meter per second

= 4.39 × 10^-3
