Answer:
Step-by-step explanation:
The both time duration should be converted to the lesser unit of time which is "minutes"
1 hour= 60 minutes
Therefore, 6 hours= 60 minutes * 6
6 hours= 360 minutes
Back to the question since the duration are in the same unit of time, we can now divide to the smallest ratio form.
40minutes/360minutes
=1/9
The final answer is 1:9
