Answer: 61.1
Step-by-step explanation: The answer would be 61.1 because .062 is greater than .05, which means that it rounds up.
Answer: The average speed is 3 mph.
Step-by-step explanation:
You would divide the distance by the amount of time it would take to get there. So in this case,
1.5/0.5=3
Let KLMN be a trapezoid (see added picture). From the point M put down the trapezoid height MP, then quadrilateral KLMP is square and KP=MP=10.
A triangle MPN is right and <span>isosceles, because
</span>m∠N=45^{0}, m∠P=90^{0}, so m∠M=180^{0}-45^{0}-90^{0}=45^{0}.Then PN=MP=10.
The ttapezoid side KN consists of two parts KP and PN, each of them is equal to 10, then KN=20 units.
Area of KLMN is egual to

sq. units.
