Correct Answer - Option 3 : 225 kms
Speed of Car = 45 kmph
Time taken by Car = 5 hours
The distance travelled or covered by a person or an object in unit time, is called its speed.
Speed = Distance Covered/Time Taken
⇒ S = D/T
where S = Speed,
D = Distance Covered
and T = Time Taken
The unit of speed is m/s or km/h or kmph.
We know that, Distance Covered = Speed × Time Taken
D = S × T
⇒ D = 45 × 5
⇒ D = 225 kms
∴ The distance between Ayush's home in the city and the village is 225 kilometres.
While finding the distance covered by a person or an object, the unit of speed and the unit of time taken should be correct i.e. if speed is in kmph then the time taken should be in hours and if speed is in m/s then the time taken should be in seconds.
