Introduction
Speed, Time and Distance is one of the most important aptitude topics. These questions help you calculate how fast an object moves, how long it takes to travel, and the distance covered during the journey.
Question 1
A car travels 120 km in 2 hours.
What is its speed?
A) 50 km/h
B) 55 km/h
C) 60 km/h
D) 65 km/h
Answer
C) 60 km/h
Explanation
Speed = Distance ÷ Time
= 120 ÷ 2
= 60 km/h
Question 2
A train moves at a speed of 80 km/h.
How much distance will it cover in 3 hours?
A) 220 km
B) 230 km
C) 240 km
D) 250 km
Answer
C) 240 km
Explanation
Distance = Speed × Time
= 80 × 3
= 240 km
Question 3
A cyclist travels 90 km at a speed of 30 km/h.
How much time will he take?
A) 2 hours
B) 3 hours
C) 4 hours
D) 5 hours
Answer
B) 3 hours
Explanation
Time = Distance ÷ Speed
= 90 ÷ 30
= 3 hours
Question 4
A bus travels at 50 km/h for 4 hours.
What distance does it cover?
A) 150 km
B) 180 km
C) 200 km
D) 220 km
Answer
C) 200 km
Explanation
Distance = Speed × Time
= 50 × 4
= 200 km
Question 5
A person covers 150 km in 5 hours.
What is the average speed?
A) 25 km/h
B) 30 km/h
C) 35 km/h
D) 40 km/h
Answer
B) 30 km/h
Explanation
Average Speed = Total Distance ÷ Total Time
= 150 ÷ 5
= 30 km/h
Key Learning
Important Formulas:
Speed = Distance ÷ Time
Distance = Speed × Time
Time = Distance ÷ Speed
These three formulas solve most Speed, Time and Distance questions.
Practice Tip
Memorize the triangle:
Distance
Speed × Time
Cover the quantity you need to find:
Distance = Speed × Time
Speed = Distance ÷ Time
Time = Distance ÷ Speed
This makes calculations quick and easy.
