Question

You drive your car for 2.0h at 40.0km/h then for 2.0 h at 60.0km/h what is your average velocity

Answer 1

Answer:

A car travels 40.0km/h in 2hrs then 60.0km/h in another 2hrs, the average velocity is $25km/h$

Explanation:

• The average speed is the ratio of total distance traveled to total time taken to cover the distance

From the question, it is given that

first traveled distance,

$d_{1} =40km/h$

time to travel this distance $t_{1} =2hrs$

very next distance traveled,

$d_{2} =60km/h$

time to travel the last journey $t_{2} =2hrs$

the total distance $d=d_{1} +d_{2}=40+60=100km/h$

total time taken for the journey $t=t_{1} +t_{2}=2+2=4hrs$

so the average velocity $V=d/t=100/4=25km/h$
