Question

A bus travels from El Paso, Texas, to Chihuahua, Mexico, in 5.2 h with an average velocity of 73 km/h to the south. What is the busâs displacement?
F. 73 km to the south
G. 370 km to the south
H. 380 km to the south
J. 14 km/h to the south

Answer 1

Answer: 380km due south

Explanation:

Velocity is the rate of change of displacement. Mathematically

Velocity = displacement/time taken

Displacement = Velocity×time taken

Given velocity = 73km/hr

Time taken = 5.2hrs

Displacement = 73km/hr×5.2hrs

Displacement = 379.6km

Approximately 380km due South
