A school recorded the number of books borrowed from the library every day for 5 days:
Day 1: \(15\) books
Day 2: \(22\) books
Day 3: \(30\) books
Day 4: \(28\) books
Day 5: \(35\) books

On a broken line graph representing this data, how many points would be plotted?

A athlete's speed (m/s) during a sprint was recorded:
0s: \(0\)
2s: \(6\)
4s: \(9\)
6s: \(9\)
8s: \(7\)
Between which two time markers is the slope of the broken line graph the steepest (regardless of direction)?

A car's fuel level (in Litres) is recorded at the end of each hour of a journey:
Hour 0: \(50\) L
Hour 1: \(42\) L
Hour 2: \(34\) L
Hour 3: \(26\) L
If the car continues to consume fuel at the same rate shown in the broken line graph, after how many total hours from the start will the fuel tank be empty?

In a broken line graph representing the sales of a shop, the points for May and June are at the same vertical height. What does this indicate about the sales for these two months?<\/p>

The following data represents the depth of water (in cm) in a tank measured every hour:
1:00 p.m.: \(25\) cm
2:00 p.m.: \(32\) cm
3:00 p.m.: \(40\) cm
4:00 p.m.: \(45\) cm
5:00 p.m.: \(48\) cm
What is the difference between the greatest hourly increase and the smallest hourly increase in water depth?

The following data shows the height of a plant measured over four weeks:
Week 1: \(5\) cm
Week 2: \(8\) cm
Week 3: \(12\) cm
Week 4: \(15\) cm
What is the difference in height between Week 4 and Week 2?

A fitness tracker recorded the number of steps a person took (in thousands) over five days:
Mon: \(6\)
Tue: \(9\)
Wed: \(7\)
Thu: \(10\)
Fri: \(12\)
Between which two consecutive days did the number of steps decrease?

A student's heart rate (bpm) was measured during and after exercise:
0 min (Start): \(70\)
2 min (Peak): \(150\)
4 min: \(110\)
6 min: \(85\)
8 min: \(75\)
Find the total decrease in heart rate from the peak to 8 minutes, and calculate the average rate of decrease per minute during this recovery period.

A shop recorded its daily ice cream sales for five days:
Monday: 50 cups
Tuesday: 45 cups
Wednesday: 60 cups
Thursday: 70 cups
Friday: 85 cups

Using this information for a broken line graph:
a) Which day had the lowest sales?
b) Which day had the highest sales?
c) What is the difference between the sales on Friday and Monday?
d) How many cups were sold in total during the first three days?

A car factory produced the following number of cars on weekdays:
Monday: 200 cars
Tuesday: 220 cars
Wednesday: 180 cars
Thursday: 250 cars
Friday: 260 cars

a) What was the total car production for the week?
b) Calculate the average daily production for these five days.
c) What is the range between the highest and lowest production days?
d) Between which two consecutive days was the production increase the largest?
e) If the production doubles on Saturday compared to the average production, how many cars will be produced on Saturday?
