Steve drove 130 miles from Portland to Tacoma in 2 hours. If he continued to drive at the same speed how long will it take him to drive 390 miles? Is it proportional

Answer:

6 hours.

Yes, time is proportional to the distance travelled.

Step-by-step explanation:

[tex]speed \: = \frac{distance}{time} [/tex]

[tex]speed = \frac{130}{2} = 65km {h}^{ - 1} [/tex]

From the formula,

[tex]time = \frac{distance}{speed} [/tex]

time = 390/65 = 6 hours.

Yes, time is proportional to the distance travelled, the more distance travelled, the more time taken at constant speed.
