Time questions are a common feature in maths exams, and they often cause confusion for students. Whether it’s working out how long a journey takes, calculating start and finish times, or converting between hours and minutes, mastering these questions is essential for exam success. In this blog post, we’ll walk you through how to approach a typical time question, with clear steps and examples. If you ever get stuck, remember that an Online GCSE Maths Tutor can provide personalised help and guidance!
1. Understand the Question
Start by carefully reading the question. Identify what times are given and what you are being asked to find. For example:
“A train leaves London at 10:35 am and arrives in Manchester at 1:15 pm. How long does the journey take?”
2. Convert Times to a Common Format
It’s usually easiest to work in the 24-hour clock or to convert everything to minutes.
- 10:35 am is 10 hours and 35 minutes.
- 1:15 pm is 13 hours and 15 minutes (in 24-hour time).
3. Calculate the Difference
Subtract the start time from the end time:
- Option 1: Work in hours and minutes.
From 10:35 to 13:15:
- From 10:35 to 11:35 = 1 hour
- From 11:35 to 13:15 = 1 hour 40 minutes
- Total: 1 hour + 1 hour 40 minutes = 2 hours 40 minutes
- Option 2: Convert both times to minutes past midnight.
10:35 am 13 \times 60 + 15 = 795 = minutes
1:15 pm 13 \times 60 + 15 = 795 = minutes
Difference: 795 - 635 = 160 minutes
Convert back to hours: 160 \div 60 = 2 hours and 40 minutes
4. Write Your Answer Clearly
The journey takes 2 hours and 40 minutes.
5. Check Your Work
Go through each step to ensure you haven’t made any mistakes with addition or subtraction.
Time questions can be straightforward if you break them down into simple steps. Practice is key! If you find these questions challenging, working with an Online GCSE Maths Tutor can help you develop strategies and boost your confidence.
Remember:
- Convert times to the same format before subtracting.
- Always check your final answer makes sense.
- Practice different types of time questions for exam success!
