Question

A train travels 16.8 km in 25 minutes find the speed of the train in
km/h

Answer 1

Answer:

Solution:

Given,

Distance covered by the train= 16.8 km

time taken = 25 minutes

\underline{\large{\textbf{Step-1:}}}

Step-1:

Express given time taken by the train in Hours.

\bigstar 1\: Hour = 60\: Minutes★1Hour=60Minutes

\implies 1\: min = \frac{1}{60}\: Minutes⟹1min=

60

1

Minutes

Multiply with 25 on both sides

\implies 25\: min = \frac{25}{60}\: Hrs⟹25min=

60

25

Hrs

\implies 25\: min = \frac{5}{12}\: Hrs⟹25min=

12

5

Hrs

time taken by train in Hrs = \frac{5}{12}\: Hrs

12

5

Hrs

\underline{\large{\textbf{Step-2:}}}

Step-2:

Find the Speed of the train in kmph

\bigstar★ Speed of the train = \dfrac{Distance\: covered}{time\: taken}

timetaken

Distancecovered

Substituting values

\implies⟹ Speed of the train = \dfrac{16.8}{\frac{5}{12}}

12

5

16.8

\implies⟹ Speed of the train = \dfrac{16.8\times 12}{5}

5

16.8×12

\implies⟹ Speed of the train = \dfrac{168\times 12}{50}

50

168×12

\implies⟹ Speed of the train = \dfrac{2016}{50}

50

2016

\implies⟹ Speed of the train = 40.32\, kmph40.32kmph

\underline{\large{\textbf{Step-3:}}}

Step-3:

Find the Speed of the train in mps

\bigstar 1\: kmph = \frac{5}{18}\: mph★1kmph=

18

5

mph

\implies⟹ Speed of the train = 40.32\, \times \frac{5}{18}\: mph40.32×

18

5

mph

\implies⟹ Speed of the train = 40.32\, \times \frac{5}{18}\: mph40.32×

18

5

mph

\implies⟹ Speed of the train = 11.2\: mph11.2mph

Answer 2

Solution:-

AnswEr:-

• The required speed of the train is 0.672 km/min.

Given:-

• Train travels 16.8 km in 25 minutes.

Find Out:-

• The required speed of the train = ?

Required Explanation:-

Formula used here:-

• Speed = Distance/Time

Putting the values according to the given formula:-

=> Required speed of the train = 16.8/25

=> Required speed of the train = 0.672

Therefore:-

• The required speed of the train is 0.672 km/min.
