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
, a is the initial amount and b is the growth factor. So our initial amount is 30 and our growth factor is 8.3. Your correct choice for this is A.
