Given:-

An electric train is moving with a velocity of 120kmph in 30 second

To Find:-

The distance

Solution:-

\begin{gathered} \bf \: Speed = \purple{ 120 \: kmph} \\ \\ \bf \:Time = 30 \: sec \\ \\ \dashrightarrow \sf \: \cancel\frac{30}{3600} hr \: \: \: \: \: \: \bigg \{ \because \:1 \: hr = 3600 \: sec \bigg \} \\ \dashrightarrow \: \pink{ \bf\frac{1}{120} hr}\end{gathered}

Speed=120kmph

Time=30sec

3600

30

hr{∵1hr=3600sec}

120

1

hr

♣ As we know that -

\begin{gathered} \mapsto \color{aqua}\boxed{ \bigstar\bf \: Distance = Speed \times Time} \\ \end{gathered}

★Distance=Speed×Time

So,

\begin{gathered} \sf \: Distance = \cancel{120 }\times \frac{1}{ \cancel{120} } \\ \bf \longrightarrow \boxed{ \bf \color{navy} \: 1 \: km}\end{gathered}

Distance=

120

×

120

1

1km
