If the area of the old garden was 1m^2, then the side lengths were both 1
if she increases the lengths by 50%, then 1 turns into 1.5
1.5 times 1.5 is 2.25
The area of her new garden is 2.25m^2
Answer:
b) 4.5 hours
Step-by-step explanation:
The first cyclist has a 3-hour head start. At 6 mph, that is an 18-mile head start.
The second cyclist gains on the first at the rate of (10 -6) = 4 mph, so will make up that 18 miles in ...
(18 mi)/(4 mi/h) = 4.5 h
The second cyclist will catch up with the first after 4.5 hours from the time the second cyclist started.
