The circle graph shows Allen’s activities during 24 hours.

How much more time in hours did Allen spend listening to music than playing tennis?
2.88 hours
0.48 hour
2.40 hours
0.12 hour

To find the difference in time spent listening to music and playing tennis, we need to calculate the difference between the two activities in hours.

From the circle graph, we can see that Allen spent 3.6 hours listening to music and 1.2 hours playing tennis.

Therefore, the difference is:

3.6 hours - 1.2 hours = 2.4 hours

Therefore, Allen spent 2.4 hours more listening to music than playing tennis.

The answer is 2.40 hours.
