Free Time Worksheets for Cambridge O Level and IGCSE
Sixteen free exam-style time questions written for Cambridge O Level and IGCSE students, and equally useful for Class 8 and 9 revision in Pakistani schools. An interactive speed, distance and time triangle calculator is included so students can check their working. Every question is pitched at secondary exam level and covers the time topics that carry marks in real Cambridge papers: all three forms of the speed formula, time zone conversions between Pakistan Standard Time and UTC, journeys that cross midnight into the next day, adding and carrying time durations, converting hours and minutes into minutes, multi-step problems such as factory shift patterns and satellite orbit counts, converting between km/h and m/s, and reading distance-time graphs. Every question has a hint and a Show Answer button. No login. No subscription. Completely free.

Key Formulas - Exam Ready!
Speed = Distance / Time
Distance = Speed x Time
Time = Distance / Speed
PKT = UTC + 5 hours
Convert hours: h x 60 = minutes
Add durations: add h, add min, carry 60
Cross-midnight: hop to 00:00 then add rest
Orbits/day: 1440 / orbit time (min)
Frequently Asked Questions
How do you convert km/h to m/s? +
Divide by 3.6. For example 72 km/h / 3.6 = 20 m/s. Going the other way, from m/s to km/h, multiply by 3.6. The 3.6 comes from 1000 metres divided by 3600 seconds.
What does the gradient of a distance-time graph mean? +
The gradient is the speed. A steeper line means faster. A flat horizontal line means stationary, because the distance is not changing. A line coming back down towards zero means returning to the start.
What is the formula for speed, distance and time? +
The three formulas are: Speed = Distance / Time, Distance = Speed x Time, and Time = Distance / Speed. Keep the units consistent. If distance is in km and speed is in km/h, the time will be in hours.
What is Pakistan Standard Time and how does UTC work? +
Pakistan Standard Time (PKT) is UTC+5, meaning Pakistan is 5 hours ahead of Coordinated Universal Time (UTC). If it is 08:00 PKT in Karachi, the UTC time is 03:00. London (UTC+0) would also show 03:00 at that moment (outside British Summer Time).
How do you calculate a journey time that crosses midnight? +
Step 1: Count from the departure time to midnight (00:00). Step 2: Subtract that from the total journey time to find what is left. Step 3: The arrival time is midnight plus the remaining time. Example: Depart 23:50, journey 8 h 25 min. From 23:50 to 00:00 = 10 min. Remaining = 8 h 25 min - 10 min = 8 h 15 min. Arrival = 00:00 + 8 h 15 min = 08:15 the next day.
How do you add two time durations? +
Add the hours together, then add the minutes together. If the minutes total is 60 or more, carry 1 extra hour and keep the leftover minutes. Example: 2 h 45 min + 1 h 50 min. Hours: 2+1=3. Minutes: 45+50=95. 95 minutes = 1 hour 35 min. Total = 3+1 = 4 hours 35 minutes.
How do you convert hours and minutes to just minutes? +
Multiply the hours by 60, then add the extra minutes. Example: 9 hours 25 minutes = (9 x 60) + 25 = 540 + 25 = 565 minutes.
How do you calculate the number of complete orbits a satellite makes per day? +
One day has 24 x 60 = 1,440 minutes. Divide 1,440 by the orbit time in minutes and round down for complete orbits. Example: orbit time = 96 minutes. 1,440 / 96 = 15. So the satellite makes 15 complete orbits per day.
