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.
