Let the time taken by computer for virus scan be, 'x' days
We are given that Computer A runs a virus scan in every 2.75 days and Computer B runs a virus scan in every 3.5 days.
<h3>Amount of work done by computer A⤵️</h3>
Amount of work done in one day = 
Amount of work done in x days = 
<h3>Amount of work done by Computer B⤵️</h3>
Amount of work done in one day = 
Amount of work done in x days = 
Since, They are doing the same work the amount of work done is 1.
Solve for x ~
➪ <em>Thus, the time taken when both computers run a virus scan at the same time again is, 1.54 days</em>
Hank is 9 years old. Explanation - What I did is I made a chart, and the categories were Sam and Hank. Then all I did was add 5 to Sam's age and added 3 to Hank's age. I repeated this until the sum of the ages equaled 24.
It has a 0.6-mile-per-minute speed limit.
<h3>What is the distance?</h3>
Distance is defined as the product of speed and time.
Given that the distance traveled in 3 seconds is 3/100 miles.
To determine the distance it can travel in 1 minute.
We must first determine the distance traveled in 1 second in order to get the distance traveled in 1 minute.
It can cover 3/100 miles in 3 seconds.
So, in 1 second it can travel = 3/(100)(3) = 1/100 miles.
Now, We know that there are 60 seconds in a minute.
Thus, it can travel in a minute.
⇒ (1/100) × 60
⇒ 60/100
⇒ 6/10
⇒ 0.6 mile
Hence, It has a 0.6 mile per minute speed limit.
