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

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
