A master baker can fill a big order in 6 hours. A student baker can fill the same order in 8 hours. They start working together, and after 2 hours, the student leaves and the master baker finishes the work alone. How long will it take him to finish the order?

It will take the master baker 2.86 hours to finish the remaining order after 2 hours.

Step-by-step explanation:

the time taken for the master baker to fill the order = 6 hours

the time taken for the student baker to fill the order = 8 hours

let the time taken for both to finish the work together if they work at the same rate = x

After 2 hours, the remaining time for them to finish the work together is given by;

t(remaining) = 3.43 hours - 2 hours = 1.43 hours

Working at the same rate, 2 persons will take 1.43 hours to finish the remaining work.

One person will take hour many hours ?

2 persons working at the same rate  --------> 1.43 hours

1 person working at the same rate -----> ?

= 2 x 1.43 hours

= 2.86 hours

Therefore, it will take the master baker 2.86 hours to finish the remaining order after 2 hours.

16 is the coefficient
