# Two machines

The first machine can produce parts in 24 hours, the second in 16 hours. The first started working in the morning at 6:00 pm. Second at 10:00 o'clock. At what hour were all parts made?

Result

x = 18:00 hh:mm

#### Solution:

$\ \\ (t-6.00)/24 + (t-10.00)/16 = 1 \ \\ \ \\ 5t = 90 \ \\ \ \\ t = 18 \ \\ \ \\ x = t = 18 = 18:00 \ \text { hh:mm }$
