Step-by-step explanation:
A)Claire runs 10 km in 1 hour.
she runs 10/2=5km in 1/2 hour.
in 2 1/2, she runs 10*2 1/2=25km
B)Malia runs 5 miles in 1 hour.
she runs 5/2=2 1/2km in 1/2 hour.
in 2 1/2, she runs 5*2 1/2=12 1/2km
Step-by-step explanation:

Since the 8 in the first number is in the thousands place, its value it 8*1000=8000.
Since the 8 in the second number is in the hundreds place, its value is 8*100=800.
8000 is ten times 800.
Final answer: 10x as large
