Question

tom left home at 7:15 am and returned at 4:45pm , for how long he away from home ? (please give step by step explanation)​

Answer 1

Answer:

9h 30min

Step-by-step explanation:

Time he left home = 7:15 am (in the morning)

Time he returned = 4:45 pm (in the evening)

So first calculating the minutes remaining in both times,

we get 8:00 - 45 minutes and 4:00 (pm) + 45 minutes.

Time range would be (12 - 8) + (4) + (2 x 45)

As eight o' clock is 4 hours behind 12pm and adding 4 because it is 4 hours ahead of the same. We are adding 45 twice as thats the time remaining after adding the main hours.

So, we will get 4h + 4h + 90min => 8h + 90min => 8h 90min

Which is also 8h (60 + 30 min) => 9h 30min..
