Question

A bus leaves a terminal traveling at a rate of 45 miles per hour. When the bus has traveled 90 miles, a car leaves the same terminal, traveling at a rate of 60 miles per hour. Which pair of equations model the distances d covered by each vehicle after t hours?

Answer 1

Bus: d1 = 60t; Car: d2 = 45t – 90

Answer 2

thats what i got

Answer 3

yes it is right

Answer 4

u sure?

Answer 5

Bus: d1 = 60t + 90; Car: d2 = 45t

Answer 6

A.

Bus: d1 = 45t + 90; Car: d2 = 60t

B.

Bus: d1 = 60t; Car: d2 = 45t – 90

C.

Bus: d1 = 60t + 90; Car: d2 = 45t

D.

Bus: d1 = 45t + 90; Car: d2 = 60t + 90

Answer 7

Answer 8

i think its A now

Answer 9

r*t = d
The following equation would be used to find t, the elapsed time for the car to intercept the bus.\[60 t=45t+90\]I hope that helps.
