Question

Train covers 20 km in one hour then how much distance will it cover in 1 min?

Answer 1

`\sf\large\underline{Given:-}`

Speed of the train = 20km / 1hr.

`\rightarrow` 1 hour = 60 minutes.

So, speed of the train = 20km/60min.

`\sf\large\underline{To\: Find:-}`

`\rightarrow`Distance covered by train in 1min.

`\sf\large\underline{Solution:-}`

Let the distance covered by train in 1 min be
`\sf{x}` m.

So, if train covers 20 km in 60min then it covers
`\sf{x}` m in 1 min.

It can be written as,

`\rightarrow`
`\sf{(20)/(60)}`
`\sf{=(x)/(1)}`(by cross multiplication)

`\rightarrow`
`\sf{20\: = \: 60x}`

`\rightarrow`
`\sf{(20)/(60)= x}`

`\rightarrow`
`\sf{(1)/(3)= x}`

`\rightarrow`
`\sf{0.33= x}`(approx)

Therefore, distance covered by train in 1 min= 0.33km (approx).
