After 15 Minutes , She turned it up to high for 30 minutes , then back down to low for 15 minutes , she then turned it off
We can see three horizontal lines
one is off - x axia
Second is low speed - 0 to 15 mins & 45 to 60 mins
Third is high speed - 15 mins to 45 mins
She started with from 0 to 15 mins = 15 mins
then she switched to high 15 to 45 mins = 45 - 15 = 30 mins
then She switched to low again 45 to 60 mins = 60 - 45 = 15 mins
then she turned it off for undefined period.
Answer:
Step-by-step explanation:
The answer seems B.
As evident from the graph for 15 min Victoria is at certain speed. But then her speed increases after 15 min for next 30 min. Then as seen from graph the speed comes back to the initial speed again for the next 15 min. Then she gets exhausted and closes the treadmill. Hence option B is correct.
The graph shows the plot of speed v/s time and the speed is maximum after 15 minutes.
