Topic :-

Conversion of Units

Given :-

A train starts from Patna on 30th May 2020 at 23:40 HRS and reaches Mumbai on 1st June 2020 at 5:15 PM.

To Find :-

Total travel time.

Solution :-

The train started from Patna on 30th May 2020 at 23:40 HRS and it reached Mumbai on 1st June 2020 at 5:15 PM.

It means train travelled on 30th May, 31st May and on 1st June.

Note : Month 'May' contains 31 days.

Calculating travel time of 30th May,

Train started at 23:40 HRS and a day gets changed as time gets 00:00 HRS.

So, time travelled =

( 60 - 40 ) minutes

20 minutes

So, travel time of 30th May is 20 minutes.

Note : 1 hour = 60 minutes

Calculating travel time of 31st May,

The train travelled whole day which means train travelled 24 hours.

Note : 1 day = 24 hours

Calculating travel time of 1st June,

Train reached Mumbai at 5:15 PM.

If time is in PM then we can convert it into HRS by adding 12:00 to it.

It means train reached Mumbai at

5 : 15 + 12 : 00 HRS

Add hours and minutes separately.

5 + 12 : 15 + 00 HRS

17: 15 HRS

It means train travelled 17 hours and 15 minutes on 1st June.

Note : If time is in AM then we can directly write it in HRS without doing any operation.

Calculating total travel time,

Time travelled on 30th May + Time travelled on 31st May + Time travelled on 1st June

20 minutes + 24 hours + 17 hours + 15 minutes

24 hours + 17 hours + 20 minutes + 15 minutes

41 hours + 35 minutes

Answer :-

So, total time travelled by train on this journey is 41 hours and 35 minutes.

Answer 2

❥ Given Data

• Train Starts from Patna on : 30th May 2020 at 23 : 40 hours
• Train Reaches to Mumbai on : 1st June 2020 at 5 : 15 PM
• Total Travel time   $\sf{--To\:Find}$

❥ Solution

$\bullet$ Train Starts from Patna on : 30th May 2020 at 23 : 40 hours

$\bullet$ Train Reaches to Mumbai on : 1st June 2020 at 5 : 15 PM

• The time when Train Reaches is given as 5 : 15 PM. It is in 12 hour format. We shall convert it into 24 hour format for Simplicity!

$\bigstar$  So, Train Reaches to Mumbai on : 1st June 2020 at 17 : 15 hours

$\longrightarrow$ From This Information we can say that, The journey has started on 30th May continued on 31st may and ended on 1st June of Year 2020. We can find the total Travel time by Adding the time spent on each specific day

Time Spent on 30th May

⇒ 60 min - 40 min = 20 min (∵  1 hour = 60 minutes)

Time Spent on 31th May

⇒ 24 hours (∵ 1 day = 24 hours ; Whole day is spent)

Time Spent on 1st June

⇒ 17 hours + 15 min (We already converted 5 : 15 PM into 24 hour Format)

━━━━━━━━━━━━━━━━━━━⠀━━━━━━━━━━━━━━━━━━━⠀━━━━━━━━━━━━━━━━━━━⠀

$:\implies$ Total Travel Time = Time Spent on 30th May + Time Spent on 31th May + Time Spent on 1st June

$:\implies$ Total Travel Time = 20 m + 24 hours + 17 hours + 15 min

$:\implies$ Total Travel Time = 24 hours + 17 hours + 15 min + 20 min

$:\implies$ Total Travel Time = 41 hours + 35 min

Total time travelled by train on this journey is 41 hours and 35 minutes
