Answer 1

Hamid: 4

Ken: 3

Explanation:

Start by finding the LCM (least common multiple) of 80 and 60. To do this we can list all the multiples of 80 and 60 until we get a common multiple.

60: 60, 120, 180, 240

80: 80, 160, 240

They both have a common multiple of 240, so after 240 seconds they will meet again at the start line.

Now we need to find how many laps they'll have to run. To do this we can divide 240 by the amount of time it takes for them to run a lap.

240/60=4

240/80=3

Hamid will have ran 4 laps and Ken will have ran 3 laps
