Multiple choice

The distance covered in fixed time interval are mentioned for four different bodies. Which of these bodies is travelling with a uniform speed?

  1. Time (s) Distance (m) 0-3 6 3-6 5 6-9 6 9-12 5 12-15 6

  2. Time (s) Distance (m) 0-3 5 3-6 5 6-11 5 11-16 5 16-20 5

  3. Time (s) Distance (m) 0-5 10 5-10 10 10-15 8 15-20 10 20-25 12

  4. Time (s) Distance (m) 0-10 20 10-20 20 20-30 20 30-40 20 40-50 20
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Uniform speed means the object covers equal distances in equal time intervals. Option D shows a constant distance of 20m for every 10s interval, indicating a constant speed of 2m/s.

AI explanation

A body is travelling with a uniform speed if it covers equal distances in equal intervals of time. Looking at the data sets, the last option shows a body covering exactly 20 meters in every 10-second interval. Since the speed remains constant at 2 meters per second throughout the journey, this body is travelling with a uniform speed.
