Quinn leaves her house at 10:00 am and runs 3 miles at a steady pace of 6 miles per

bogdanovich [222]

Using the relation between velocity, distance and time, it is found that Quinn returns home at 1 pm.

Velocity is distance divided by time, that is:

$v = \frac{d}{t}$

She walked 3 miles at a velocity of 6 miles per hour, thus $d = 3, v = 6$ . The time is:

$v = \frac{d}{t}$

$t = \frac{d}{v} = \frac{3}{6} = 0.5$

Thus, she arrived at 10:30 am, and took a lunch break of 1 hour, so she started to return at 11:30 am.
Distance of 3 miles, velocity of 2 miles per hour, thus $d = 3, v = 2$ . The time she took to return, in hours, is:

$t = \frac{d}{v} = \frac{3}{2} = 1.5$

1.5 hours after 11:30 am is 1 pm, thus, Quinn returns home at 1 pm.

Answer:

sqrt(3/8) = t

.61237 = t

Step-by-step explanation:

h(t)=−16t^2+10

Let h(t) = 4

4 =−16t^2+10

Subtract 10 from each side

4-10 =−16t^2+10-10

-6 = -16 t^2

Divide by -16

-6/-16 = t^2

3/8 = t^2

Take the square root of each side

sqrt(3/8) = sqrt(t^2)

sqrt(3/8) = t

.61237 = t

We only take the positive since time is not negative
