BARB Distance Speed and Time 1 — Questions and Answers
Question 1: A soldier runs 12 kilometres at a constant speed of 6 km/h. How long does the run take?
- 1 hour
- 3 hours
- 2 hours (Correct answer)
- 1.5 hours
Correct answer: 2 hours
Time = Distance ÷ Speed = 12 ÷ 6 = 2 hours.
Question 2: A convoy travels for 3 hours at 50 km/h. What distance does it cover?
- 100 km
- 200 km
- 150 km (Correct answer)
- 175 km
Correct answer: 150 km
Distance = Speed × Time = 50 × 3 = 150 km.
Question 3: A patrol covers 90 km in 2 hours. What is its average speed?
- 40 km/h
- 50 km/h
- 45 km/h (Correct answer)
- 60 km/h
Correct answer: 45 km/h
Speed = Distance ÷ Time = 90 ÷ 2 = 45 km/h.
Question 4: Vehicle A travels at 60 km/h and Vehicle B travels at 40 km/h. Both start at the same point at the same time. After 2 hours, how far apart are they?
- 40 km (Correct answer)
- 20 km
- 60 km
- 80 km
Correct answer: 40 km
Vehicle A covers 120 km and Vehicle B covers 80 km, so they are 40 km apart.
Question 5: A soldier must travel 75 km and has 1.5 hours. What minimum speed is required?
- 50 km/h (Correct answer)
- 45 km/h
- 60 km/h
- 55 km/h
Correct answer: 50 km/h
Speed = Distance ÷ Time = 75 ÷ 1.5 = 50 km/h.
Question 6: Which formula correctly expresses the relationship between distance (D), speed (S), and time (T)?
- D = S + T
- S = D × T
- D = S × T (Correct answer)
- T = D × S
Correct answer: D = S × T
Distance equals speed multiplied by time: D = S × T.
