Answer:
2/6 or simpler 1/3
Step-by-step explanation:
Answer:
6 miles
Step-by-step explanation:
Let the distance of Boondocks from Podunk to be x
1/3 x +1 = 1/2x
1=1/2x-1/3x
1= 1/6 x
6*1=x
6 miles= x
Speed (S) = Distance (D) / time (t)
First stretch
45 = D / 2
D = 45*2
D = 90 mp
How is the same distance:
Second stretch
S = 90 / t
Average speed (AS):
AS = (S1+S2) / 2
60 = [45+(90/t)] / 2
120 = 45+90/t
120-45 = 90/t
75 = 90/t
t = 90/75
t = 1,2 h
________________________
And now:
S = 90 / t
S = 90 / 1,2
S = 75 mph
Y=x-5
6=x-5
6+5=x-5+5
11=x
x=11
