Question

Define the speed of an object.

A car covers a distance of 50 km in two hours. Calculate the speed of a car.​

Answer 1

Answer:

➡speed is the distance travelled by an object with respect to time

➡The distance travelled by the car

$\large{50km/h\:X\:2h}$

$\large{100km}$

Answer 2

Speed is defined as the total distance travelled by an object per unit time.

The answer to the numerical question is :-

d=50km
t=2

Now the speed can be measured in two S I Units- km/hour and m/s.
The calculation in km/hr is as follows:-

Speed= Distance/Time
V= d/t
= 50/2
= 25 km/hr
