45

Explanation:

We know that Jennifer's home and her mother's house are separated by a distance (in miles) d.

The average speed is

.

So, her Saturday average speed is:

And her Sunday average speed is

Now, we also know that

Taking this in consideration, we can replace in the second equation

Now, this is equal to the first equation:

Working a little

Puting this in the second equation

Taking out the units

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
