Car A is traveling east at a steady speed of 60 miles per hour after 2 hours, it is 130 miles east of Johnstown. car B is traveling east on the same road. its distance east of Johnstown is represented by the graph.
Please help!

Answer: A

Step-by-step explanation:

Car B was 10 miles east of car A.

The rate of change of position of an object in any direction is called speed.

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

According to the given question

Speed of car A was 60 miles/hour.

⇒ After 2hours the distance covered by car A = 60 × 2 = 120 miles.

But it is given that car travelled total 130 miles.

So, the extra distance covered by the car = 130 - 120 = 10 miles.

From the graph we can say that the distance.

At, Time = 0

The distance travelled by car B is 20 miles.

Now, the extra distance covered by the car A w.r.t B = 20 - 10 = 10 miles

Since, both the cars were travelling in east direction.

Therefore, Car B was 10 miles east of car A.
