Answer:
9 seconds.
Step-by-step explanation:
On your graph, use a ruler and your eye to get the best fitting line.
Then find the time in seconds (45) which is between 40 and 50 on the x axis.
Go across to the y axis. You will find it is about 9 seconds.
so first lets make the denominators the same so that we can divide
1/3 = 2/6
5/6
if you divide johny can make 2 cups of serving and R 1/5
