Answer:
<u><em>28 minutes.</em></u>
Step-by-step explanation:
We can see from our graph that 12 minutes after starting the race Lynn left Kael behind and he ran at a greater speed till the race ended after 40 minutes.
To find total number of minutes Lynn ran faster than Kael we will subtract 12 from 40.
Therefore, Lynn ran at a greater speed than Kael for <u><em>28 minutes.</em></u>
Let e=erasers and p=pencils. So we know the total amount of erasers plus pencils sold is equal to 220. Therefore,

We also know the cost of erasers and pencils totaled to $695 in earnings and so:

and so those are your two equations.
