Car A and car B take part in a race around a circular track. One lap of the track measures 7.6 km.
Car A takes 2 minutes and 40 seconds to complete each lap of the track.
Car B takes 2 minutes and 25 seconds to complete each lap of the track.
Both cars travel at a constant speed.
(a) Calculate the speed of car A.
Give your answer in kilometres per hour.
km/h [3]
(b) Both cars start the race from the same position, S, at the same time.
(i) Find the time taken when both car A and car B are next at position S at the same time.
Give your answer in minutes and seconds.
I
min
s [4]
(ii) Find the distance that car A has travelled at this time.

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.  

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group

the answer is: -22 also a
