Answer:

a) 9 miles

b) 6 miles

c) 3 miles

Step-by-step explanation:

a)  Clare's speed = 12 mph

Calculate Clare's speed in miles per minute by dividing 12 by 60 (as there are 60 minutes in an hour):

12 ÷ 60 = 0.2 miles per minutes

Therefore, position after 45 minutes:  45 x 0.2 = 9 miles

b) Han's speed = 8 mph

Calculate Han's speed in miles per minute by dividing 8 by 60 (as there are 60 minutes in an hour):

8 ÷ 60 = 2/15 miles per minutes

Therefore, position after 45 minutes:  45 x 2/15 = 6 miles

c) Distance between Clare and Han = 9 - 6 = 3 miles
