Problem of the Week (Mar 25-Mar 29)

Mar 24, 2019 | Country Hills

Happy Sunday everyone!  It's a little dreary out there after the week of spectacular weather so here are the problems of the week to brighten your day!  Students, don't forget to have your answers in to me by next Sunday to qualify for the draw.

Grade 1-3:

Question: Jake plays his viola for at least 20 minutes each day. Each song he plays is 3 minutes long. What is the least amount of time Jake can spend playing the viola so that he finishes the song he’s playing at the 20-minute mark? How many songs does he play?

Grade 4-6:

Question: Finn is 15 decimetres tall and casts a 45-decimetre shadow. Jake is 71/2 decimetres tall. If Jake stands on top of Finn’s head, how tall will their shadow be?

Grade 7-9:

Question: Bonnibel is doing an experiment in her chemistry lab, but the labels on the ingredient containers of cinnamaldehyde, dextrose, glycerin, and sapodilla tree sap have peeled off. She knows that the cinnamaldehyde isn’t in either of the two largest containers, and the sapodilla tree sap isn’t in either of the two smallest containers. The ingredient in the second smallest container doesn’t have a smell, so it can’t be either dextrose or cinnamaldehyde. The last letter on the label of the second largest container hasn’t peeled off all the way, and it’s an “e.” Match the ingredients with their containers.

Grade 10-12:

Question: Simon has a magic crown that allows him to fly. He can fly 24 kilometres per hour when the weather is calm. If Simon flies straight from the top of a mountain that is 3/4 of a kilometre tall to the ground 1 kilometre west of his initial location, then how long will it take him to reach the ground?
