Answer:
8 miles
Step-by-step explanation:
I'm going to assume the question said that she "couldn't" repair the tire and was forced to walk back home, that makes more sense.
With that in mind:
She rode her bike 2 miles.
She walked 4 miles on the way there, and 6 miles on the way back.
You can deduce that it was a 6 mile walk back because of the 2 mile bike ride, then the 4 mile walk that it took to get there.
All in all that rounds out to 10 mile walking, and 2 mile biking. That is 8 miles more walking than biking.
Answer:
D
Step-by-step explanation:
Let point Q = (4,y)
√[ (4-0)^2 + (y-0)^2 ] = √[ (6-0)^2 + (0-0)^2 ]
Square both side
(4-0)^2 + (y-0)^2 = (6-0)^2 + (0-0)^2
4^2 + y^2 = 6^2
16 + y^2 = 36
y^2 = 36-16
y^2 = 20
y= √20
y= 2√5
