Today my math's group and I had to do some problem solving with our fun teacher. Down below you will see the problem and the strategies me and my little group had discussed together.
2kg = 80 mins
3kg = 2 hrs
4kg = 2 hrs 40 mins
We then add the time with the time we put
the roast in at and finally we have the time
it will be ready:) >> 2 hrs + 9:50 am = 11:50 pm + 40 mins = 12:30 pm
+ 9:50 am = 11:50 pm + 40 mins = 12:30 pm
