Answer 1

Three workers, A, B, and C are working in a bicycle factory. A

finishes assembling a bike every 1 h 30 min. B finishes

assembling a bike every 2 h. C finishes assembling a bike

every 1 h. If they started assembling three bikes at the same

time at 8:10, at what time would they start assembling at the

same time again? Give your answer in a 24-hour clock format,

such as 19:00.

we have that

A

1 h 30 min=1.5 hours

the sequence is

1.5 3 4.5 6 7.5 9 10.5 ....

B

2 hours

2 4 6 8 10 12 14 16 ...

C

1 h

1 2 3 4 5 6 7 8 9 10 ...

Compare the sequences

in 6 hours A, B and C has finished assembling three bikes

so

they don't start assembling at the same time again
