I had to phone up my son the computer whiz in LA to help me out on this one. They owed him some time in the massively parallel processor center where he works, and he ran this calculation for me last night. Here's what he came up with:

1 hour = 60 minutes

0.9 hours = (0.9 x 60) = 54 minutes

90 minutes is equal to 1 and a half hours, or 1 hour and 30 minutes. In terms of hours, you can express this as 1.5 hours

A machine puts C caps on bottles in m minutes. How many hours will it take to put caps on B bottles?

If we let the time it takes to put a single cap on a bottle = "t", then we are told: t = m / C We want our answers in hours, so we'll convert that, adjusting the for the relationship between minutes and hours. We know that there are sixty minutes in an hour, so we can say: t = (h / 60) / C t = h / 60C Again, that's the time it takes to apply a single cap. To apply "B" caps then, would take: t = Bh / 60C or B/60C hours.
