D.68
A squared plus b squared equals c squared and so add the two lengths given and square them which gives you the hypotenuse squared so then find the square root of your result which is 68
It would be 6 miles per hour.
mph is a unit for speed. And the formula for speed is s=distance /time
So the distance is 2 miles
And the time is 20 minutes
*for this question you need to convert the minutes to hours to get the right units
20mins =0.3 hours (approx) [20/60 to get it in hours]
2 miles/0.3 hours ≈ 6 mph

Step-by-step explanation:
see the attached figure with letters to better understand the problem
we know that
In the right triangle ABD

In the right triangle BCD

remember that
m< BAD=m<CBD
therefore

equate the equations



It is in the first quadrant
