There are 14 times in the table.  Add up all 14 times, and divide the sum by 14.  The result is the "mean 100-meter sprint time," assuming that you've rounded this off to the nearest tenth of a second.

Find the deference between
maxonik [38]

Answer:

$5520

Step-by-step explanation:

Given data

Principal=  $24000

Rate=10%

time= 2 years

Firstly, the compound interest is given as

A=P(1+r)^t

A=24000(1+0.1)^2

A=24000(1.1)^2

A=24000*1.21

A=$29040

The simple interest is given as

A=P(1+rt)

A=24000(1+0.1*2)

A=24000(1.2)^2

A=24000*1.44

A=$34560

Hence the difference is

=34560-29040

=$5520

Estimate the time Juanita will arrive at her aunt's home 320 miles away if she leaves at 9:00 a.m., drives about 60 miles per ho
uranmaximum [27]

Answer:

D. 3:00 p.m.

Step-by-step explanation:

d = Distance = 320 miles

s = Speed = 60\ \text{mph}=\dfrac{60}{3600}=\dfrac{1}{60}\ \text{miles/s}

Time taken is given by

t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{320}{\dfrac{1}{60}}\\\Rightarrow t=19200\ \text{s}

40 minutes break is 40\times 60=2400\ \text{s}

Total time taken is 19200+2400=21600\ \text{s}=\dfrac{21600}{60\times 60}=6\ \text{hours}.

So, the entire trip took 6 hours. 6 hours after 9 a.m. is 3 p.m.
