Answer:

13:20

Explanation:

Start time:

  • 09:30

Trip duration:

  • 3 hr 50 min

End time= ?

Solution 1

Simply adding up the time the family left and time in trip:

  • 09:30 + 03:50 = 13:20

Sum of minutes:

  • 30 min + 50 min = 80 min = 1 hr and 20 min

Sum of hours:

  • 09 hr + 03 hr = 12 hr and add 1 hr from line above = 13 hr

So time arrival is:

  • 13:20

Solution 2

Time they left is 09:30 and it will take 2 hr and a half before noon.

Splitting 3 hr and 50 min into two parts, one part being 2 hr and 30 min and the other is:

  • 3 hr 50 min - 2 hr 30 min = 1 hr 20 min

Adding 2 hr 30 min and then adding 1 hr 20 min to initial time of 09:30:

  • 09 : 30 + 02:30 = 12:00

Then:

  • 12:00 + 01:20 = 13: 20 this is arrival time of family
