Answer:
3 km
Step-by-step explanation:
30 divided by 10 is 3.
9 divided by 3 is 3.
Therefore, your answer is 3.
The center is (-2,0)
The radius is -3
Since Emily is walking at a constant speed, we can solve this using proportions, equating ratios of distance/time.
The first ratio is 3/4 miles/1/4 hour
The second ratio is 1 mile/ x hour
Equating the two ratios: 3/4 / 1/4 = 1/x
3 = 1/x
x = 1/3 hour
