89+90=171. keep in mind that increased or increased by means to add
1/6 of an hour is 10 minutes because there are 60 minutes in an hour so 60/6=10
so it's 25m^2/10minutes
now just multiply 25 by 12 ( 12 lots of 10 minutes in 2 hours)
25*12=300
answer is 300m^2
hope this helped
The second equation, its setup is correct
26 27 28 29 30 so 25 24 23 22 21---so 30 is the awnser
Because when divided a fraction u must flip a fraction and cross multiply
1/2÷5/6
1/2×6/5
3/5
