question 10 , on page 61

10) Trevor rode his mountain bike 84 km in 3 h. Jillian rode 70 km in 2.5 h. Who has the faster cyclist ? How do you know ?










Trevor and Jillian are the same, so they have the same speed .
I knew because I did the T chart to see who has the fastest cyclist .

Coin Math
If the pennies were stacked how tall would they be ?
100mm : 50pennies
2mm : penny

50/50 = 1
100mm/50 = 2mm



Part 2
1) What would the recipe look like if it had to serve 10 people? Show your calculations.

10 ÷ 4 = 2.5

ground beef - 0.5 x 2.5 = 1.25 lb
medium onion, diced - 1 x 2.5 = 2.5
stalk celery finely diced - 1 x 2.5 = 2.5
clove garlic, minced - 1 x 2.5 = 2.5
canned tomatoes, chopped - 14 x 2.5 = 35 oz
can tomato paste - 0.5 x 2.5 = 1.25
parsley - 1 x 2.5 = 2.5 tsp
basil - 1.5 x 2.5 = 3.75 tsp
oregano - 1 x 2.5 = 2.5 tsp
sugar - 1 x 2.5 = 2.5 tsp
Worcestershire Sauce - 0.5 x 2.5 = 1.25 tsp
seasoning salt - 0.5 x 2.5 = 1.25 tsp
bay leaf - 1 x 2.5 = 2.5



2) What would the recipe look like if you had to only serve 1 person? Show your calculations.

10
÷ 1 = 10

ground beef - 1.25 ÷ 10 = 0.125 lb
medium onion, diced - 2.5 ÷ 10 = 0.25
stalk celery finely diced - 2.5 ÷ 10 = 0.25
clove garlic, minced - 2.5 ÷ 10 = 0.25
canned tomatoes, chopped - 35 ÷ 10 = 3.5 oz
can tomato paste - 1.25 ÷ 10 = 0.125
parsley - 2.5 ÷ 10 = 0.25 tsp
basil - 3.75 ÷ 10 = 0.375 tsp
oregano - 2.5 ÷ 10 = 0.25 tsp
sugar - 2.5 ÷ 10 = 0.25 tsp
Worcestershire Sauce - 1.25 ÷ 10 = 0.125 tsp

seasoning salt - 1.25 ÷ 10 = 0.125 tsp
bay leaf - 2.5 ÷ 10 = 0.25
