Question

5. If a bus travels 120 miles and travels at 35 miles per hour, how long will the trip take?

Answer 1

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.

Answer 2

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
