Answer:
1) 45 minutes or 0.75 hours
2) 45 minutes or 0.75 hours
Step-by-step explanation:
We are given the graph that shows Miriam's bike ride.
The x-axis represents the time (in minutes) and the y-axis represents the distance traveled in miles.
1) How many hours did Miriam stop to rest?
The graphs stays the same from 45 minutes to 90 minutes, where he took the rest. No distance covered in that time.
Rest time = 90 minutes - 45 minutes = 45 minutes
He took rest for 45 minutes.
In hours, it is 45/60 = 0.75 hours
2) How many hours did it take Miriam to bike the initial 8 miles.
Look at the graph, the graph reached 8 miles when the time was 45 minutes.
It took 45 minutest to reach 8 miles initially.
In hours, it is 45/60 = 0.75 hours
