What is the question to number 3! explain it to me!

answer:

it's b 1.9 miles.

step-by-step explanation:

the shortest distance is found using the pythagoras theorem. we have a right angled triangle and the shortest distance is the hypotenuse, h : -

h^2 = 0.9^2 + 1.7^2 = 3.7

h = √3.7

h = 1.924.

The answer should be -19/13 per hour. I think, I'm not completely sure.

Step-by-step explanation:

Find the difference of 9 1/4 and 4 1/2

divide by 3 1/4

simplify

4 1/2 - 9 1/4 = -19/4

-19/4 divided by 13/4 = -76/52

-76/52 = -38/26 = -19/13

So the answer should be -19/13 per hour.
