Sydney Pierce · Answer 1

Step-by-step explanation:

Let the distance be D and time T.

D ∞ T

D = kT

Where k is the constant of proportionality.

k = D/T

When D = 270miles & T = 6hours

k = 270/6

k = 45

: - D = 45T

When T = 8hours

D = 45 * 8

D = 360miles

Answer: 360 miles

Explanation: to find how fast the vehicle is going you have to decide 270 by 6 and you get 45 miles per hour, after this you have to add 2 hours to 6 which one hour being 45 that means 2 hours is 90 miles, now add 90 to 270 and you get 360
