Answers
Given data : Soham needs to reach a place which is 20 Km away from his home. He rides his bike at a speed of 40 Km per hour.
To find : How much time Soham will take to reach the place?
Solution : Let, Soham rides his bike at a constant speed of 40 km/hr.
Now we use formula of speed,
⟹ speed = distance/time
⟹ 40 = 20/time
⟹ time = 20/40
⟹ time = ½ hour
{More info :
- 20 km = 20000 m
- 40 km/hr = 40000/3600 = 11.11 m/s
⟹ speed = distance/time
⟹ 11.11 = 20000/time
⟹ time = 20000/11.11
⟹ time = 1800.18 sec
Here we know
- 1800.18 sec = 30 minutes}
Answer : Time taken by Soham to reach the place is ½ hour (30 minutes).
