Two bicycles head toward each other from opposite ends of a freeway 468 kilometers long. if the speed of the first bicycle is 22 kilometers per hour and the speed of the second bicycle is 17 kilometers per hour, how long will it take before the bicycles pass each other?

goog may have it for you

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
