Answer 1

Q1
Divide each distance by its time to find the speed for each driver.
T: 380 km / 4 hr = 95 km/h
M: 530 km / 5 hr = 106 km/h
Martine's average speed was greater.

Q2
Bronze to aluminum is 25:2
The alloy is bronze plus aluminum, so by adding 25 + 2 you get 27.
Bronze to total is 25:27

25 is 27 as x is to 55

25/27 = x/55

27x = 25 * 55

x = 50.926

Answer: 50.926 kg of bronze

Q3
Manipulative toys to art toys is 30:40
Total toys = 30 + 40 = 70

manipulative toys are 30 out of 70

30/70 * 100 = 42.9%
