ok let me explain it properly

Answer 3

ok

Answer 4

u have 6 teachers that mark 36 papers in 90 minutes

so first we work out how many papers one teacher can mark in one hour or 60 minutes.

what we do is:

36 / 90 = 0.4 per minute

now to get the answer for one hour we multiply by 60

0.4 * 60 = 24

but we need to work out how much per teacher so we divide that by 6

24 / 6 = 4 papers per teacher per hour

now we need to work out how many papers would get marked with 8 teachers
so you multiply that by 8

4 * 8 = 32 papers in one hour (oops my bad good u told me to show working out first answer was incorrect done in a hurry :p)

so the answer is 32 papers with 8 teachers in one hour
