FAST-NU Basic Mathematics — Speed, Time and Work
Speed, Time and Work is part of the Basic Mathematics section of FAST's BS CS/Engineering admission test (usually 20 of the 120 MCQs, 20% of the marks). It breaks into 2 subtopics, and we hold 57 FAST-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Speed, Time and Work MCQs from the FAST-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · FAST Past Paper 07 · Speed, Time and Work
If the speed is doubled, the time taken to cover the same distance is:
- A.doubled
- B.unchanged
- C.four times as long
- D.halved
Show answer
Answer: D. halved — Time = distance ÷ speed, so doubling the speed halves the time.
- Q2 · FAST Past Paper 06 · Speed, Time and Work
A speed of 1 km/h means covering:
- A.1 km in 1 hour
- B.1 m in 1 hour
- C.1 km in 1 minute
- D.1 m in 1 second
Show answer
Answer: A. 1 km in 1 hour — km/h = kilometres per hour.
- Q3 · FAST Past Paper 05 · Speed, Time and Work
The SI unit of speed is:
- A.km
- B.hour
- C.kg/s
- D.m/s
Show answer
Answer: D. m/s — Speed = distance ÷ time, so its SI unit is metre per second.
