Question.
a) 55km/hr
- 110 ÷ 2= 55 /2 ÷ 2h = 1


b) 64km/hr
- 800 ÷ 12.5 = 64 / 12.5 ÷ 12.5 = 1



c) 1.5 daffodils/ 1min
- 45 ÷ 30 = 1.5 / 30 ÷ 30 = 1

They are going an equal amount of speed. 28km/hr

Part 2:

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
tsp 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
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
tsp 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
bay leaf - 2.5 ÷ 10 = 0.25
