Hint:
Try using an online source to get the answer. Like a program.
As Mikaela is running 5km in 0.5 hours, as you're looking for an hour, you double it. Therefore, she can run 10km in 1 hour.
As she bikes 20km in 0.8 hours- she bikes 5km in 0.2 of an hour, therefore, she bikes 25km per hour.
If she continues at this rate, she will travel 35km in 2 hours.
A) 10km
B) 25Km
C) 35 KM
Hope this helps :)
