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

    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

    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.

    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

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

    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

    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
