Questions with solutions
Q1 — Speed Calculations · easy · theory
The speed of an object is found using which formula?
A. Speed = Time ÷ Distance
B. Speed = Distance × Time
C. Speed = Distance ÷ Time ✓ Correct
D. Speed = Distance + Time
Solution: Speed is the distance travelled divided by the time taken.
Q2 — Speed Calculations · easy · numerical
A car travels 100 metres in 20 seconds. Its speed is:
A. 20 m/s
B. 120 m/s
C. 2 m/s
D. 5 m/s ✓ Correct
Solution: Speed = distance ÷ time = 100 ÷ 20 = 5 m/s.
Q3 — Speed Calculations · easy · theory
Which of these is a unit of speed?
A. kilogram (kg)
B. metre per second (m/s) ✓ Correct
C. degree Celsius (°C)
D. second (s)
Solution: Speed is distance over time, so its unit is metre per second (m/s).
Q4 — Speed Calculations · easy · numerical
A boy walks 12 metres in 3 seconds. His speed is:
A. 9 m/s
B. 36 m/s
C. 4 m/s ✓ Correct
D. 15 m/s
Solution: Speed = distance ÷ time = 12 ÷ 3 = 4 m/s.
Q5 — Speed Calculations · medium · numerical
A runner covers 200 metres in 25 seconds. His speed is:
A. 8 m/s ✓ Correct
B. 10 m/s
C. 5 m/s
D. 175 m/s
Solution: Speed = distance ÷ time = 200 ÷ 25 = 8 m/s.
Q6 — Speed Calculations · medium · numerical
A cyclist moves at a speed of 10 m/s for 5 seconds. The distance covered is:
A. 50 m ✓ Correct
B. 15 m
C. 5 m
D. 2 m
Solution: Distance = speed × time = 10 × 5 = 50 m.
Q7 — Speed Calculations · medium · numerical
A bus travels 60 km at a speed of 30 km/h. The time taken is:
A. 90 hours
B. 1 hour
C. 2 hours ✓ Correct
D. 30 hours
Solution: Time = distance ÷ speed = 60 ÷ 30 = 2 hours.
Q8 — Speed Calculations · medium · theory
Car A moves at 40 km/h and Car B at 60 km/h on the same road. Which car is faster?
A. Car B ✓ Correct
B. Car A
C. Cannot be said
D. Both are equal
Solution: A higher speed means faster, and 60 km/h is greater than 40 km/h, so Car B is faster.
Q9 — Speed Calculations · hard · numerical
A train covers 240 km in 4 hours. Its speed is:
A. 60 km/h ✓ Correct
B. 120 km/h
C. 80 km/h
D. 40 km/h
Solution: Speed = distance ÷ time = 240 ÷ 4 = 60 km/h.
Q10 — Speed Calculations · hard · numerical
Which is faster, an object moving at 5 m/s or one moving at 3 m/s, and by how much?
A. Both are the same
B. The 3 m/s object, by 2 m/s
C. The 5 m/s object, by 2 m/s ✓ Correct
D. The 5 m/s object, by 8 m/s
Solution: 5 m/s is greater than 3 m/s, and the difference is 5 - 3 = 2 m/s.
