Question

anakin finish your mathematics portfolio in 3 hours while bella can finish the job in 5 hours if they teacher asked them to to work together in finishing the mathematics porfolio,how long will it take them to finish the work​

Answer 1

Step-by-step explanation:

Time taken by Anakin to finish the work = 3 hours

Fraction of work finished in 1 hour by Anakin = 1/3

Time taken by Bella to finish the work = 5 hours

Fraction of work finished in 1 hour by Bella = 1/5

Work completed in 1 hour by Anakin and Bella together = 1/3 +1/5 = (5+3)/15 = 8/15

Therefore, they can complete the work together in 15/8 hours = 1.875 hours
