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.

Elf · Answer 1

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
