Question 5.
A train starts at 7:40 A.M. and reaches its destination at 2:15 p.m. How much time it will takes to complete its journey. Find out the time interval of journey.
Solution:
The time when the train starts the journey = 7:40 AM
The time gap from 7:40 AM to 8:00 AM = 20 mins
The time gap from 8:00 AM to 12:00 Noon = 4 hours
The time gap from 12:00 Noon to 2:00 PM = 2 hours
The time gap from 2:00 PM to 2:15 PM = 15 mins
Total time = 6 hours 35 mins
The time interval of journey = 6 hours 35 mins
Second Method :
The time when the train starts the journey = 7:40AM = 7 : 40 hours
The time when the train reaches its destination = 2 : 15 PM
= 2 : 15 + 12 : 00
= 14 : 15 hours
Therefore, the time interval of journey = 6 h 35 mins
Question 6.
Shikha starts her journey by car at 6:40 A.M. and completes her journey at 3:50 p.m. How long did she drive the car ?
Solution:
The time when Shikha starts the journey = 6:40 AM
The time gap from 6:40 AM to 7:00 AM = 20 mins
The time gap from 7: 00 AM to 12:00 Noon = 5 h
The time gap from 12:00 Noon to 3:00 PM = 3 h
The time gap from 3:00 PM to 3:50 PM = 50 mins
The time for which she drives the car = 8 hours 70 mins
= 8 hours + 70 mins
= 8 hours + 60 mins + 10 mins
= 8 hours + 1 hour + 10 mins
= 9 hours 10 mins
Second Method:
The time when Shikha starts the journey = 6 : 40 AM 6 : 40 hours
The time when Shikha reaches her destination = 3 : 50 PM
= 3:50+ 12:00
= 15:50 hours
Question 7.
A cricket match starts at 9:30 p.m. and ends at 1:25 a.m. For how long did the match continue?
Solution:
The time when the cricket match starts = 9:30 PM
The time gap from 9:30 PM to 10:00 PM = 30 minutes
The time gap from 10:00 PM to 12:00 mid night = 2 hours
The time gap from 12:00 mid night to 11:00 AM = 1 hour
The time gap from 1:00 AM to 1:25 AM = 25 minutes
The time for which match continues = 3 hours 55 minutes
Question 8.
Sunny starts his bhangra practice at 4:15 p.m. For how long did he practice for bhangra?
Solution:
The time when sunny starts his bhangra practice = 4:15 PM
The time gap from 4:15 PM to 5.00 PM = 45 minutes
The time gap from 5:00 PM to 6:00 PM = 1 hour
The time. gap from 6:00 PM to 6:10 PM = 10 minutes
The time spent for practice = 1 hour 55 minutes
Second method:
Because starting time and finishing time both are in PM
∴ Therefore, the the spent by Sunny for practice = 1 hour 55 minutes
