Jared and Pedro walk 1 mile in about 15 minutes. They can keep up pace for several hours. About how far they walk in 65 minutes

<h2><u>Answer:</u></h2>

Jared and Pedro walked a total of <u>4.3 miles</u>

<h2><u>Step-by-step explanation:</u></h2>

The equation for distance is <u>speed = distance ÷ time.</u>
Rearrange the equation to make distance the subject:

<em>(multiply both sides by time)</em>

<em> </em><u>Distance = Speed × Time</u>

Convert your numbers into suitable units:

1 mile ÷ 15 = <u>0.06m/minute</u>

Finally, substitute the numbers into the equation and solve:

Distance = 0.06 × 65 = <u>4.3miles</u> (rounded to the nearest decimal place)

Please help me answer this. I think that for the first one the answer is A, but I am not sure. There are two parts to the questi

Vector $PQ=(7-5, 3-4)=(2, -1)$ . $4RS=4 \cdot (4-8, 1-6) = 4 \cdot (-4, -5) = (-16, -20)$ . So the sum is $(-14, -21)$ .

For the second, the magnitude is the square root of the sum of the squares of the components. This is equal to $\sqrt{(-14)^2+(-21)^2} = \sqrt{637}=7\sqrt{13}$ .
