Question

A train travels 55km, south along a straight track in 34minutes. What is the train Ls average velocity in kilometers per hour

Answer 1

96.5 km/h

Step-by-step explanation:

The average velocity of the train is given by:

`v=(d)/(t)`

where

d is the displacement

t is the time taken

For this train, we have:

d = 55 km south (displacement is a vector, so we must also consider the direction)

`t= 34 min \cdot (1)/(60 min/h)=0.57 h`

Substituting into the equation, we find the average velocity:

`v=(55 km)/(0.57 h)=96.5 km/h`
