Answer:

3.43 hrs

Explanation:

Assuming the bus needs to travel 120 miles in total;

It has an average velocity of 35 mi/hr and a total distance of 120 mi.

We can use the equation for displacement:

  • d = v_(avg) * t  
  • Notice this is the area under the curve of a velocity vs time graph.

The displacement of the bus is 120 miles and its average velocity is 35 mi/hr. Substitute these values into the equation.

  • 120 = 35 * t
  • t = 120/35
  • t = 3.43 hours

The trip will take 3.43 hours for the bus to travel a total distance of 120 miles.

Speed = Distance/Time

  • we have speed and distance from the question;

Now,

35 = 120/t

35/120 = 1/t

120/35 = t

3.42 hours = t
