9-64.

Scooter rides his skateboard every day after school. He often stops to do tricks. On Monday, he rode for $2$ hours and went $3$ miles. By the end of the week, he had gone a total of $11$ miles, which took him a total of $9$ hours.

1. Did he ride the same time and distance every day after school? Justify your answer.

If Scooter rides the same time and distance every day after school, his weekly ratio will be an equivalent fraction to his daily ratio.

For example, from Monday to Wednesday:

 Monday Tuesday Wednesday Hours $2$ $2$ $2$ Miles $3$ $3$ $3$ Total Hours $2$ $4$ $6$ Total Miles $3$ $6$ $9$

Is the weekly ratio an equivalent fraction to Scooter's daily ratio?

No, $2:3$ is not equivalent to $9:11$.

2. Which was faster, his rate on Monday or his average rate for the week? How do you know?

Try completing the table above for the rest of the week.
Do the total hours over the total miles in your table match the actual total hours over total miles ($9$ over $11$) that Scooter traveled throughout the week?
