Question

QI. Read the following passage and choose the correct answer:
The distance travelled by an object per unit time (either in one hour, in one minute or in
one second) is known as speed of the object. A slow-moving object is said to have a low
speed and a fast-moving object is said to have high speed. So, if we know the distance
covered by two buses in one hour, then we can answer which one is slower. Therefore, the
formula for calculating the speed of an object can be given by
Speed = Distance travelled Time taken
1.
A bus travels 54 km in 90 minutes. The speed of the bus is:
(a) 0.6 m/s
(b) 10 ms
(c) 5.4 ms
13.
3.6 m's
II. The correct symbol to represent the speed of an object is:
sms
(b) 5 mp
(c) 5 ms
(d) 5 sm
III. If the speed of an object moving along a straight line keeps changing, its motion is
said to be
(a) uniform motion
(b) non-uniform motion
vorlinear motion
(d) none of these
IV. The speed of the vehicle is recorded by:
(a) Odometer
(Speedometer​
