4. Sunita leaves home for school at 10 minutes to seven and comes back home at ten past 2. Howlong does she stay in school?
Answers
Answer:
3 hours and 12 minutes.
Explanation:
Sunita stays in the school for 3 hours and 12 minutes.
Given data :
She leaves the school at 10 minutes to seven.
She comes back home at 10 past 2.
• Now,we have to calculate the time gap between her departure and arrival.
• So,her departure time
= 10 minutes to seven
= 6:50 (minutes to means remaining time before the given time)
• So, her arrival time
= 10 past 2
= 10:02 (past means already leftover time to the given time)
• So,now we have to calculate the time gap between 6:50 to 10:02,in order to calculate the total time she stays in the school.
• Now,we can use the simple hourly method of calculation.
• The starting time is 6:50.
So,in round off hour figure,the nearest time to the ending time (10:02) is 9:50.
• Now,the round off figure is in the 3 hours gap from the starting time.
And,12 minutes less than the ending time.
• So,the time difference = 3 hours 12 minutes
She,stays in school for 3 hours and 12 minutes.
