FAQs on Speed, Time & Distance: Races & Escalators Video Lecture - Quantitative Aptitude (Quant) - CAT

1. How can I calculate the speed of a runner in a race?
Ans. To calculate the speed of a runner in a race, you can use the formula: Speed = Distance/Time. Measure the distance the runner covers in the race and the time it takes them to complete it, then divide the distance by the time to get the speed.
2. How do I determine the time taken by a runner to finish a race if I know the speed and distance?
Ans. To determine the time taken by a runner to finish a race if you know the speed and distance, you can use the formula: Time = Distance/Speed. Simply divide the distance by the speed to get the time taken.
3. How can I calculate the distance covered by a runner in a race if I know the speed and time taken?
Ans. To calculate the distance covered by a runner in a race if you know the speed and time taken, you can use the formula: Distance = Speed x Time. Multiply the speed by the time taken to get the distance covered.
4. Can I use the concept of speed, time, and distance to calculate the speed of an escalator?
Ans. Yes, you can use the concept of speed, time, and distance to calculate the speed of an escalator. Treat the escalator as a moving walkway and calculate the relative speed of a person walking on the escalator compared to standing still on it.
5. How can I calculate the time it takes for a person to climb up an escalator if I know the speed of the escalator and the person's speed?
Ans. To calculate the time it takes for a person to climb up an escalator if you know the speed of the escalator and the person's speed, you can use the formula: Time = Distance/(Speed of Person + Speed of Escalator). Divide the distance by the sum of the person's speed and the escalator's speed to get the time taken.
