Logan worked 7 hours and Sarah worked 6 hours. Sarah has to work within the multiples of to for it to be an even number such as 2 4 6 hours which equal 70 140 and 210 which end in 0’s. Guess and check. Sarah 210 shirts = 6 hours. Logan 280 shirts = 7 hours
(I think) Logan worked 7hrs and ironed 280 shirts whilst Sarah worked 6hrs and ironed 210 shirts.
