a train covered a distance of 41 km ,36km nd 43km in three consecutive hour. find the average distance covered by a train in one hour
Answers
Answer:
Speed = Distance / Time
The train speed is given in km/hr, but the question asks for distance travelled in minutes.
A straight rearranging of the equation has a problem. The units for time are different but we can sort this out by converting km/hour into km per minute. Then
Speed (km/min) * Time (minutes) = Distance (km)
How do we do this?
An hour is 60 minutes - so 36 km/ hr is the same as 36 km /60 minutes.
So in 3 minutes the train will travel 3 * (36/60) km, or 1.8 km.
Edit:
If you know that 3 mins is 1/20 of an hour, you'd simply divide the 36 km by 20 to get the same answer.
