Answer:
Chucks spent 8 minutes running and 15 minutes swimming
Step-by-step explanation:
Here, we want to know the amount of time Chuck spends on individual activities.
since the total time spent for the burning is 23 minutes;
then ;
r + w = 23 ••••••••(i)
Now, the number of calories burnt to running for r minutes will be r * 35 = 35w calories
The number of calories burnt to swimming for w minutes will be w * 30 = 30w calories
The addition of both gives the total calories burnt;
Hence;
35r + 30w = 730 ••••••••(ii)
So we have two equations to solve simultaneously ;
From i; r = 23-w
Substitute this into ii
35(23-w) + 30w = 730
805 -35w + 30w = 730
35w -30w = 805-730
5w = 75
w = 75/5
w = 15 minutes
but r = 23 - w
r = 23 -15
r = 8 minutes
They all can be split up to 6 groups because 12+18=30 so each group will have 5 kids in it.

➷ Work out the cost per gram
60/125 = 0.48
It costs 0.48 cents per gram
Multiply this by 100 to get the answer:
0.48 x 100 = 48
It would cost 48 cents
