CPM Homework Help : MC2 Problem 11-54

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 and it took him a total of $9$ hours. Did he ride the same time and distance every day after school? Justify your answer.

Help:

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

Hint:

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?

Answer:

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