How much will it cost to drive from Montreal to Niagra Falls?

Math Level:

Junior High (Grades 7 - 9)

Here is the scenerio:

Next month we're planning a trip from Montreal to Niagra Falls. My husband is going to run the Niagra Falls marathon, so we're going for the weekend.

Our car uses about 1 gas tank (50L of gas) for approximately 600km. The distance from Montreal to Niagra falls is 667km (you could get the students to look this up as an extra challenge). Also I plan to drive around in Niagra falls a bit (at least 84km, as I have to drive my husband to the start of the Marathon, which is 42km long, and then come back to the finish line in Niagra Falls).

How much penicillin to give to a 900lb bull?

Math Level:

Junior High (Grades 7 - 9)

While visiting a farm, a bull had broken his penis. In order to help him with the healing process and any infections that would come from this terrible incident, the farm hand had to administer penicillin to him. On the bottle, there was a dosage of penicillin per 1kg. But she only knew the weight of the animal in pounds --> 900lbs. So she asks... how many kilograms in 900lbs?
