Worked Solution & Example Answer:The distance between Bricktown and Koala Creek is 75 km - HSC - SSCE Mathematics Standard - Question 3 - 2020 - Paper 1
Step 1
Calculate the time taken for the journey
Answer
To determine how long it takes to complete the journey, we can use the formula:
ext{Time} = rac{ ext{Distance}}{ ext{Speed}}Substituting the given values:
Distance = 75 km Speed = 50 km/h
Thus:
ext{Time} = rac{75 ext{ km}}{50 ext{ km/h}} = 1.5 ext{ hours}To convert 1.5 hours into hours and minutes:
1.5 hours is equivalent to 1 hour and 30 minutes.
Therefore, the correct option is C. 1 hour 30 minutes.
