This is dd's maths homework - usually dh explains it as I'm useless at maths although year 4 shouldn't be a problem [shame]
She has to show her way of finding the answer to this: Train leaves at 11:25 on Wednesday, arrives on Thursday at 0:42. How long was the journey? She can figure it out by counting the hours and adding the minutes and then adding both together but what is the 'official' way of showing how she figured it out?
Does it say if it's am or pm? - if pm they might wat her to show the minutes up to midnight, then the minutes after midnight, then add them together.
But if it's am I'd just do it the way you've described and do the hours and then the minutes - there may not be a "proper" way of doing it anyway, sometimes they just want to see how you went about it.
Ok so she figured out it's 13 hours from 11am to midnight then 25 and 42 minutes makes 67 minutes so 1hour and 7 minutes but the actual sum to show how she got 13 hours (and later add 1hour 7 minutes) is the problem, how to write it?
The 25 plus 42 are easy to show as a sum, but the hours 11am to 12pm?
Thanks alot - I can work it out now but dd doesn't understand it . I'd rather send the homework in with it not done so the teacher knows. She's inherited my hate love of maths and has been trying really hard but this throws her back into thinking she can't do anything.
12 pm wednesday to 12 am thursday is 12 hours (this i think is meant to be the hardest bit of the question as many people find the 24 hour clock confusing) 12hrs + 35min + 42min = 12 hrs + 77mins = 13 hrs + 17 mins
I think it's how muminscotland described it. Has your dd not done additions by jumping along a line? First jump is 11.25 to 12.00. Second jump is from 12.00 to 00.00 and third jump from 00.00 to 00.42. Then you add them all up.
Agree though, if she doesn't understand then write a note
