QUESTION 10 : PAGE 60

10. Trevor rode his mountain bike 84 km in 3 hours. Jillian rode her mountain bike 70 km in 2.5 hours. Who is the faster cyclist ?. How do you know ?

Trevor: 84/3 = 28km/hour.

Jillian: 70/2.5 = 28 km/hour.

so you know that they were going the same speed.

Question 4: PAGE 60

4. Determine the unit rate in each situation.

a) An orca swims 110 km in 2 h.55/hour

b) A Canada goose flies 800 km in 12.5 h.19.3/hour

c) Cathy plants 45 daffodils in 30 min.1.5/mins.

PART 2:

1) What would the recipe look if you had to serve 10 people ?
Show your calculations.

Ground beef - 0.5 x 2.5 = 1.25 lb
Medium Onion diced - 1 x 2.5 = 2.5
Stalked celery finely diced - 1 x 2.5 = 2.5
Clove garlic minced - 1 x 2.5 = 2.5
Canned tomatos chopped - 14 oz x 2.5 = 35
Canned 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 - o.5 x 2.5 = 1.25 tsp
Seasoning Salt - o.5 x 2.5 = 1.25 tsp
Bay leaf - 1 x 2.5 = 2.5

All I did was multiply all the original numbers by 2.5 to get the answer !.

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

Ground beef - 1.25 ÷ 10 = 0.125 lb
Medium Onion diced - 2.5 ÷ 10 = 0.25
Stalked celery finely diced - 2.5 ÷ 10 = 0.25
Clove garlic minced - 2.5 ÷ 10 = 0.25
Canned tomatos chopped - 35 ÷ 10 = 3.5
Canned 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
