Answer:
4.2
Step-by-step explanation:
Divide 1000 by 236 and you will get that result.
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
3 is n and that is the answer
3k-2=2k+4
-2k. -2k
k-2=4
+2. +2
k =6
