x mile=42 min
cross multiply
x=3/28

cross multiply
42 x 3/28 =21 x 3/14
=3 x 3/1
=9
The answer is 9 miles

<h3>What is Probability ?</h3>
Probability is the likeliness of an event to happen ,
It has a range from 0 to 1 , where 0 indicates uncertainty while 1 indicates certainty
The data for the college students is given and it has been asked to determine P(0)
The total students are 200
and the students that have no credit card from the data is 122
Therefore
P(0) = 122/200 = 0.61
Therefore the probability that number of credit cards is 0 is 0.61

Ratio of boys to girls= 17:3
number of people= 740
to find the number of boys out of 740 people, you have to add the ratio together and divide 740 by it. then multiply the answer by 17 because the ratio for boys is 17.
17+3=20
740÷20=37
37×17=629
