Speeding Problems
Use the formulas for average speed and average velocity to answer the following problems:
1 Nilo drives his van with an average velocity of 45.0 km/h along the North Luzon Expressway. How long will it take him to drive 350 km on a perfectly straight highway?
2. A tourist bus moves at an average velocity of 60.0 km/h for 0.500 h. What is the total displacement of the bus?
Answers & Comments
Answer:
1. the time it takes for Nilo to drive 350 km at an average velocity of 45 km/h is 7.778 hours or 466.68 minutes.
2.
V = d/t
V = 60km/h
t = 0.500h
d = ?
D = V/t
D = 60km/h ÷ 0.500h
D = 30km
the bus had a displacement of 30km.
Explanation:
1. Considering Nilo drives in a perfectly straight path, we can find the time it takes for him to to drive 350 km through the velocity formula given below:
v =
v is for velocity
d is for distance
t is time
To find time t
t =
t = (350 km)/(45 km/h) → this cancels out km unit leaving us with h unit
t = 7.778 hours
Hence,
the time it takes for Nilo to drive 350 km at an average velocity of 45 km/h is 7.778 hours or 466.68 minutes.
Answer:
1. The time it takes for Nilo to drive 350 km at an average velocity of 45 km/h is 7.778 hours or 466.68 minutes.
Considering Nilo drives in a perfectly straight path, we can find the time it takes for him to to drive 350 km through the velocity formula given below:
v = \frac{d}{t}td
v is for velocity
d is for distance
t is time
To find time t
t = \frac{d}{v}vd
t = (350 km)/(45 km/h) → this cancels outkm unit leaving us with h unit
t = 7.778 hours
Hence,
the time it takes for Nilo to drive 350 km at an average velocity of 45 km/h is 7.778 hours or 466.68 minutes
2. A tourist bus moves at an average velocity of 60.0 km/h for 0.500 h. What is the total displacement of the bus is
