Answer:
5.71428571422 m/s
Explanation:
u = Initial velocity = 20 m/s
v = Final velocity
s = Displacement
a = Acceleration
Time taken = 15-1 = 14 s
Distance traveled in 1 second = 


The speed as she reaches the light at the instant it turns green is 5.71428571422 m/s
The P value for the given data set is 25127. For finding P value, we have to must find the Z value.
<h3>How to get the z scores?</h3>
If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
The Z value is calculated as;

Z = (X - μ) / σ
Z = (4.007 - 3.6) / 0.607
Z = 0.67051
The P value for the given data set is 25127.

Answer:
Explanation:
given data= 34.2 m/s
we have to convert it into km/s
as we know that
1 km=1000 m
so 1 m= 1/1000 =0.001 km
now we know that 1 min=60 sec
so 1 sec=1/60= 0.016 min
therefore
34.2m/s = 34.2*m/sec =34.2*0.001 km /0.016 min
so 34.2 m/s =2.1 km/min
