Question

If it takes 37 minutes 58 seconds to complete a task, how long would it
take to repeat the same task 7 times (answer in hours, minutes and
seconds)?

Answer 1

I got the hours but I am finding it hard getting the seconds

Answer 2

if you have the hours, just multiply it by 3600 to get the seconds!

Answer 3

No thats that the answer, its meant to be in hours, minutes and seconds. I have found the hours part just cant change it to the rest

Answer 4

well.. here is the answer..
the time taken to complete one task, in seconds is 37*60+58=2278sec
the time to do 7 tasks 7*2278=15946sec.

Answer 5

I got all of that then divided bY 3600

Answer 6

the time in minutes=15946/60=265.77 min
the time in hours=4.43 hours

Answer 7

so what do you exactly want?

Answer 8

this is the time it takes to do 7 tasks, in hours, minutes and seconds

Answer 9

No u dont get it. these are the answer choice

a 4 hours 26 mins 0 secs
b 3 hours 45 mins 46 secs
c 4 hours 25 mins 46 secs
d 4 hours 66 mins 15 secs

Answer 10

I see

Answer 11

(37 min*7) + (58sec*7)

259min + 406 sec ..... maybe :)

Answer 12

O.O that looks nice actually

Answer 13

259/60 = 4hrs and 16 minutes

Answer 14

ok..
4.43 hours=4 hours +0.43*60 min=4 hours 25.8 min=4 hours 25min 48sec

Answer 15

406/60 = 6minutes and 46 seconds i think

Answer 16

4 hours 22 minues and 46 seconds if I did it right... which is a BIG if today :)

Answer 17

the difference is due to the approximation I made in an earlier step :)

Answer 18

the answer is c

Answer 19

anistre64 your answer is not in the options

a 4 hours 26 mins 0 secs
b 3 hours 45 mins 46 secs
c 4 hours 25 mins 46 secs
d 4 hours 66 mins 15 secs

Ok got it now.. Thank you

Answer 20

its close... accounting for errors in my stupidity :)

Answer 21

it's exactly c.. I double checked it

Answer 22

yep XD.

Thanks again

Answer 23

259/60 was off a bit...4 hours 19 minutes

Answer 24

4.19.0 + 0.6.46

4.25.46 is right...

Answer 25

nice, you way seems shorter and easier as well.

thanks

Answer 26

Kadious, do you know how to do it anyway? for next times? :P

Answer 27

i think its the same, just constructed differently,,,, :)

Answer 28

yep, I got up the 4.43 hours bit but didnt know how to get the mins and seconds

Answer 29

But now I got the idea. Basically to multiply the 0.43 by 60 then if there are any remainder, I mulitply by 60 again

Answer 30

instead of going on into the decimals, keep the remainder of the division to "see" whats left :)

Answer 31

Hmm .. sounds and seems harder.

Answer 32

another way is to "estimate" the time to 38 minutes; then subtract from that 7*2secs ......

38 * 7 = 266 minutes

266/60 = 4hrs with a remainder of 26minutes

-7*2 secs = -14 sec

4 hrs 25 min and 46 sec

Answer 33

oh thats nice. so basically the the 2 is the 60-58 and 7 is the "7 times" thingy.

So its basically the same as the other one you did

Answer 34

yep..

Answer 35

nice ,

Thanks XD
