The equation d=rt is used to calculate distance, rate, or time, where d is the distance (in miles), r is the rate (in miles per hour), and t is the time (in hours). consider the statements below that describe the driving rates for three people. graph the equation that represents the rate of the fastest person. braylon drives at a rate of 50 miles per hour. kiko drives for 9 hours and goes 405 miles. presley drives 385 miles in 7 hours.

Presley is the fastest

d= 55t

Step-by-step explanation:

d= rt

Divide by t

d/t =r

so we can find the rate

Braylon

50 miles per hour

Kiko

rate = distance/ time

         = 405 miles / 9 hours

          = 45 miles per hour

Presley

rate = distance/ time

         = 385 miles/ 7 hours

          = 55 miles per hour

Presley is the fastest

d =rt

d = 55 t

Remember t >=0 since it is time

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
