Practice question
Question
A bus moves at a constant speed of 36km/h for 30minutes. What is the distance covered?
Explanation
Convert speed: 36km/h=36⋅10003600=10m/s. As per NCERT Chapter 3, equations v=u+at, s=ut+½at², v²=u²+2as describe uniformly accelerated motion. Applying correct signs and units gives 18 km as the result, so option A is correct.
