Answer:
Given,
Owen had three different kinds of stickers that he wanted to put on paper.
He put a bird sticker on every 30th paper, a sports sticker on every 50th paper and a robot sticker on every 60th paper.
Multiples of 30 = 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, 450, 480, 510, 540, 570, 600.
Multiples of 50 = 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600
Multiples of 60 = 60, 120, 180, 240, 300, 360, 420, 480, 540, 600
So, the common multiples are 300 and 600.

Running the Race

Use an open number line to model and solve problems 1 and 2.

Question 1.
Anna started a race at 9:30 am. She ran for 3 hours and 47 minutes. What time did she finish her race?
Answer:
Given,
Anna started a race at 9:30 am. She ran for 3 hours and 47 minutes.
9 hour 30 mins
3 hour 47 mins
12 hour 77 mins
= 13 hour 17 mins
So, the race ends at 1:17 P.M.

Question 2.
Michael and Tyler both ran a half marathon. Michael finished in 1 hour 42 minutes and 13 seconds. Tyler finished in 97 minutes and 49 seconds.
a. Who was faster?
Answer:
Given,
Michael and Tyler both ran a half marathon. Michael finished in 1 hour 42 minutes and 13 seconds.
Tyler finished in 97 minutes and 49 seconds.
1 hour = 60 minutes
97 minutes = 60 + 37 = 1 hour 37 minutes
So, Typer was faster.

b. How much faster was he?
Answer:
(1 hour, 42 minutes 13 seconds) – (1 hour, 37 minutes, 49 seconds)
4 minutes, 24 seconds.
Tyler was 4 minutes and 24 seconds faster than Michael.

Question 3.
Takumi ran the first mile of his race in 450 seconds. How many minutes was his first mile?
Answer:
Given,
Takumi ran the first mile of his race in 450 seconds.
60 seconds = 1 min
450/60 = 45/6 = 15/2 = 7.5 minutes
Tamuki ran the first mile of his race in 7.5 minutes.

Question 4.
Johanna used tiles to build a rectangular array with an area of 54. List all the possible dimensions of the array.
Answer:
Given,
Johanna used tiles to build a rectangular array with an area of 54.
54 = 54 × 1, this is the first probability
54 = 27 × 2, this is the second probability
54 = 18 × 3, this is the third probability
54 = 9 × 6, this is the fourth probability
There are four probabilities that can be there.

Question 5.

Question 8.
CHALLENGE Linda plans to sign up for three Field Day events. She wants to run a total of more than a kilometer but less than 1.5 kilometers. Which three events should she sign up for? Her choices are:
Bridges in Mathematics Grade 4 Home Connections Unit 4 Module 3 Answer Key 2
Answer:
To find the best combination of events for Linda to sign up for to run a total of more than a kilometer but less than 1.5 kilometers, we must first determine the total distances of the individual events.
Depending on the events offered, Linda can choose three events that add up to more than a kilometer but less than 1.5 kilometers.
If Linda has the option of running the 100m, 200m, and 800m, she can satisfy her requirement of running more than a kilometer but less than 1.5 kilometers by choosing the 100m, 200m, and 800m.
Add up to 1100m, which is over a kilometer but below 1.5 kilometers.
Another option for Linda is to run the 100m, 400m, and 600m, which would add up to 1100m, once again satisfying her requirement.
