So how many seconds does it take the ant to travel 1 meter?

anonymous · Answer

10 seconds.

jamesj · Answer

No.  There are 100 cm in a meter.

jamesj · Answer

Leave the answer in seconds for now.

anonymous · Answer

Oh yeah. So 100 centimeters is 100 seconds

jamesj · Answer

Right and hence how long for 50 meters?

anonymous · Answer

5000 seconds.

jamesj · Answer

Right.  Now convert that into hh:mm:ss

jamesj · Answer

Hint: 1 hour = 60 minutes = 60x60 seconds = 3600 seconds

jamesj · Answer

Therefore 5000 seconds = 1 hour + mm minutes and ss seconds.

anonymous · Answer

My answers aren't making sense.

jamesj · Answer

Well subtract out one hour and we have
5000 - 3600 = 1400 seconds.  

Now how many complete minutes are there in 1400 seconds?

anonymous · Answer

23

jamesj · Answer

Right, so
5000 seconds = 1 hour + 23 minutes + ss seconds.

What's the remainder, the number of seconds, ss?

anonymous · Answer

20

jamesj · Answer

right.
