Convert the speed of train to km/hour its speed is 25 m/sec also find distance covered by the train in 20 minutes.
Answers
Answer:
- The speed of train is 90 km/hour.
- Distance covered by the train in 20 minutes = 30 km
Step-by-step explanation:
Given that:
- Speed of a train = 25 m/sec
To Find:
- Speed of the train in km/hour.
- Distance covered by the train in 20 minutes.
Converting the speed in km/hr:
In one second distance travelled = 25 m
We know.
- 1 hour = 3600 seconds
In 3600 seconds distance travelled = (25 × 3600) = 90000 m
We know that.
- 1000 m = 1 km
- 90000 m = 90000/1000 = 90 km
In 1 hour distance travelled = 90 km
∴ The speed of train is 90 km/hour.
Converting the 20 minutes into hours:
We know that.
- 60 minutes = 1 hour
- 20 minutes = 20/60 = 1/3 hours
Finding the distance covered by the train in 20 minutes:
We have.
- Speed = 90 km/hour
- Time = 1/3 hours
We know that.
- Distance = Speed × Time
⟶ Distance = 90 × 1/3
⟶ Distance = 30
∴ Distance covered by the train in 20 minutes = 30 km
Answer:
Given :-
Speed = 25 m/s
Distance covered = 20 min
To Find :-
Distance covered
Solution :-
Distance covered in m/s
=> 25 × 60 × 60
=> 25 × 3600
=> 90,000 m
In km
1000 m = 1 km
90000 m = 90 km
Now,
According to the question
20 min = 20/60 hrs
Distance = 90 × 20/60
Distance = 90 × 2/6
Distance = 180/6
Distance = 30 km
