Best answer
Correct Answer - Option 3 : 225 kms

Given:

Speed of Car = 45 kmph

Time taken by Car = 5 hours

Concept:

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.

Calculation:

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.
