One person can do a certain job in ten minutes, and another person can do the same job in fifteen minutes. How many minutes will they take to do the job together?If x represents how many minutes to do the job together, then how much of the job does the slowest person do?
Answers
Answer:
They will take 6 minutes to do the job together.
Slowest person do 2/5 of the total work.
Step-by-step explanation:
Given,
Time taken by first person = 10 minutes,
⇒ One day work of the first person = ,
While, time taken by second person = 15 minutes,
⇒ One day work of second person = ,
So, when both persons work together, total one day work = ,
Thus, the total time taken by the both persons when they work together,
x = = 6 minutes
The one who takes more time is slower.
Now, the part of the work done by the slowest person ( second one),
So he can do 1/10th of the job in 1 minute
Similarly another person can do 1/15th of the job in 1 minute
Together they can do in 1 minute = 1/10 +1/15 = 5/30 = 1/6th of the job
So together they can finish the job in 6 minutes. ANSWER
slowest person does x/ 15 th of the job ANSWER
1/6 +1/2 +1/3 = 7/6
together they can do the job in 6/7 days

500 * 0.000000001 = 0.0000005 Giga seconds
Final answer:
500 seconds equates to 0.0000005 gigaseconds. This is determined by dividing 500 seconds by 1,000,000,000 seconds (the number of seconds in a gigasecond).
Explanation:
In the field of physics, the measure of time can be broken down into various units. The smallest unit is the second. Higher units include kiloseconds, megaseconds, and gigaseconds. One gigasecond (Gs) is equal to 109 seconds or 1,000,000,000 seconds.
To convert 500 seconds into gigaseconds, you need to divide 500 by 1,000,000,000.
So, 500 seconds = 500 / 1,000,000,000 Gs.
This calculation results in 0.0000005 Gs, which is your answer.
