Question

For a car moving at a constant speed, the distance traveled varies directly with the time spent driving. If such a car travels 270 miles in 6 hours, how many miles does it travel in 8 hours?

Answer 1

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

Answer 2

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
