Let us consider the distance between kensington and greenwich be x
since the given figure is a right angled triangle,we use pythagoras theorem to find the answer

so by pythagoras theorem
x^2= 20^2+40^2
x^2=400+1600
x^2=2000

x=root of 2000=20root 5mi
answer is option (b)

After riding her bike for 20 miles. Angela got off and walked her bike the rest of the way at 5 miles per hour. If the total tri
mylen [45]

Answer:

She rode her bike 20 miles... I believe this may be a trick question.

Step-by-step explanation:

Let's break down this problem...

If she is going at a rate of 5 miles per hour while walking than the maximum she could have walked in 5 hours is 25 miles.

If Angela rode her bike for 20 miles, and the got off her bike and walked "<em>the rest of the way</em>" then she should have walked 50 miles. However as we already know her rate is 5 miles per hour while walking, and therefore could only have covered half that distance in 5 hours.

Is this a multiple choice question? Is there any misssing informaation?

Step-by-step explanation:

A(3, 7)

B(7, 10)

As we move from A to B, we see x increasing by 4 to 7 and y increasing by 3 to 10.  Thus the slope is
