Question

A body moving with uniform speed travelled a distance of 120 m in 20 seconds. Find its speed.

Answer 1

Answer:

6m/s

Explanation:

GIVEN- distance- 120m

time- 20 seconds

TO FIND- speed

CONCEPT- speed= distance/time

speed= 120m/20

= 6m/s

FINAL ANSWER- 6m/s

Answer 2

Answer:

Concept:

The speed (also known as v) of an object is indeed the magnitude of the rate of change of its location with time or the magnitude of the movement of its position per unit of time, making it a scalar quantity in everyday usage and kinematics. The instantaneous speed is the upper limit of the average speed as the length of time interval approaches zero. The average speed of an item in a period of time is equal to the distance travelled by the different items by the duration of the period. The parameters of speed are time divided by distance.

Given:

A body moving at a constant speed covered 120 metres in 20 seconds.

Find:

Find its speed.

Answer:

Given that

$distance = 120m$

$time = 20 seconds$

$speed=\frac{distance}{time}$

         $=\frac{120}{20}$

$speed = 6 m/s$

Speed is what it means. the speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Speed is calculated as follows: speed = distance / time. Knowing the units for distance and time is necessary to calculate the units for speed. The units will be in metres per second (m/s) in this example since the distance is measured in metres (m) and the time is measured in seconds (s).
