Sketch of graph of pendulum on moon?
The question as asked is tough to answer without some assumptions... The question implies that a comparison is being made to the action of the same pendulum on earth. With that assumption... The graph I assume has time on the x-axis and a form of pendulum oscillating measurement (such as height or back (-1) to forward (+1) ) on the y-axis. The period ( time from peak to peak on the y-axis ) of the pendulum on the moon compared to the same on earth will be 6 times longer assuming that gravity on the moon is 1/6th that of earth. The reason why the period is longer is that the acceleration (gravity) on the moon is much less. This causes the pendulum on the moon to move back and forth less quickly.

I know that 0.6 of an hour equals 40 minutes but how do you work this out?
.6 of an hour is not 40 minutes, it is 36 minutes. This is worked out by multiplying the decimal and the amount of minutes in an hour.
.6 x 60 = 36 minutes
Example
.5 x 60 = 30 minutes, half of an hour equals half of an hour.
