Grade 9: taco cart

Today we looked at the taco cart problem.  We noticed the information given in the video, and asked questions about what information was missing, or what problems we could solve.

We had some discussion about the relationship between the hypotenuse and the legs (perpendicular triangle sides), and remembered that the pythagorean theorem is going to be helpful.

We had to incorporate different walking speeds, and ratios were a good way to approach it.

We figured out answers in the end, and had a look at the final video to confirm our calculations.  Some of us made errors along the way, and we learned lots from these errors.

Good work today!
