Answer 1

Given that,

A train started from Chandigarh for new delhi.

Suppose, we find at what time did the train start from Chandigarh?

Train started from Chandigarh and after 1 hour 45 minutes, train halted at Karnal for 35 minutes.

We need to calculate the total time

Using formula for time

$T=t_{1}+t_{2}$

Where, $t_{1}$ = after travel time

$t_{2}$ = stay time at Karnal

Put the value into the formula

$T=1\ h:45\ min+0\ h:35\ min$

$T=2\ h: 20\ min$

If the train left Karnal at 11:40 am

We need to calculate the time when the train start from Chandigarh

Now, we reduced the total time from 11:40 am

$T'=11:40-2:20$

$T'=9:20\ am$

Hence, The train started from Chandigarh at 9:20 am.

Answer 2

at what time it reached karnal
