Question

. A machine can fill 300 bottles in 4 hours. How much time will be
required for six such machines to fill 9000 bottles?​

Answer 1

Answer:

120 is answer of your question

Answer 2

Answer: 20 hours.

Step-by-step explanation:

The rate at which this machine operates is 300/4

=75 bottles per hour.

first, we should distribute the  number of bottles equally among the 6 machines.

so one machine gets 9000/6 bottles

=1500 bottles each

if they operate together at the same time, (assuming they operate simultaneously) we can simply find the time taken for one machine to fill 1500 bottles.

since one machine can fill 75 bottles an hour,

it will take 1500/75 hours for one ,machine to fill 1500 bottles.

1500/75

=20 hours
