The graph mentioned in the question above is shown in the figure attached below:
Answer:
- 45 minutes = 0.75 hours
-
45 minutes = 0.75 hours
Explanation:
In the figure below you can see that the graph does not show any change between 45 and 90 minutes, during the distance covered in that period of time. This means that to know how many hours Mirian stopped to rest, we need to do the calculation:
Rest time: 90 minutes - 45 minutes = 45 minutes
45 minutes / 60 = 0.75 hours.
To find out how many hours it took Miriam to ride her bike in the initial 8 miles, we must see in the graph that Miriam reached 8 miles after 45 minutes, that is, it took 45 minutes for her to reach 8 miles.
45 minutes / 60 = 0.75 hours.
We divide the minutes by 60, because 1 hour has 60 minutes.
