Q1. A train travels 120 km in 3 hours. What is its speed?
A) 30 km/h
B) 40 km/h
C) 50 km/h
D) 60 km/h
Correct Option is: B) 40 km/h
Explanation:
Speed = Distance ÷ Time
= 120 ÷ 3
= 40 km/h
Q2. If a car moves at 72 km/h, how many meters will it cover in 5 seconds?
A) 80 m
B) 90 m
C) 100 m
D) 120 m
Correct Option is: D) 100 m
Explanation:
Speed in m/s = (72 × 1000) ÷ 3600 = 20 m/s
Distance = Speed × Time = 20 × 5 = 100 m
Q3. A person walks 10 km in 2 hours. What is his speed?
A) 4 km/h
B) 5 km/h
C) 6 km/h
D) 3 km/h
Correct Option is: B) 5 km/h
Explanation:
Speed = 10 ÷ 2 = 5 km/h
Q4. If a bus covers 180 km in 4 hours, what is its average speed?
A) 36 km/h
B) 40 km/h
C) 45 km/h
D) 50 km/h
Correct Option is: C) 45 km/h
Explanation:
Speed = 180 ÷ 4 = 45 km/h
Q5. How long will a car take to cover 240 km at a speed of 60 km/h?
A) 3 hours
B) 4 hours
C) 5 hours
D) 6 hours
Correct Option is: B) 4 hours

Time = Distance ÷ Speed
= 240 ÷ 60
= 4 hours
Q6. A train is 150 meters long and crosses a pole in 15 seconds. What is its speed?
A) 9 m/s
B) 10 m/s
C) 12 m/s
D) 15 m/s
Correct Option is: B) 10 m/s
Explanation:
Speed = Distance ÷ Time
= 150 ÷ 15
= 10 m/s
Q7. Two trains running at 40 km/h and 60 km/h are moving in opposite directions. How long will they take to cross each other if each is 120 m long?
A) 6.48 sec
B) 7.2 sec
C) 8.64 sec
D) 9.6 sec
Correct Option is: C) 8.64 sec
Explanation:
Relative speed = (40 + 60)
= 100 km/h
= 100 × (1000/3600)
= 27.78 m/s
Total distance = 120 + 120 = 240 m
Time = 240 ÷ 27.78 ≈ 8.64 sec
Q8. A cyclist covers a distance in 3 hours at 20 km/h. What distance did he cover?
A) 50 km
B) 60 km
C) 70 km
D) 80 km
Correct Option is: B) 60 km

A) 30 mins
B) 1 hour
C) 45 mins
D) 20 mins
Correct Option is: B) 1 hour
Explanation:
Time at 60 = 180 ÷ 60 = 3 hours
Time at 90 = 180 ÷ 90 = 2 hours
Time saved = 1 hour = 60 minutes
Oops! So, correct answer is B) 1 hour
Q10. A train covers 600 km at a speed of 75 km/h. How long will it take?
A) 6 hours
B) 7 hours
