Answer 1

Step 1:

Question 1.1

Arrive time = 7:30

Departure time = 17:00

`\text{Total time spent = 17:00 - 7:30 = }9\colon30`

h (9:30) > 7

Garage B is cheaper

Question 1.2

Arrive time = 8:23

Departure time = 10:53

`\text{Total time spent = 10:53 - 8:23 = 2: 30}`

The time spent by issac and his friends is between 2 < h < 4

Since h = 2:30

Answer R11.00

Question 1.3

Karabo uses Garage B

Time spent is 4 < h < 6
