I guess " 18 43" means 18:43 hours.
If the slower press runs x per hour, then
(18 + 43/60)(x + x+200) = 75000
Now finish it off
In a printing works, 75 000 leaflets are run off by two printing presses in 18 43 hours. One press delivers 200 more leaflets per hour than the other. Find the number of leaflets produced per hour by each of the machines.
