Question

alex drives with an average velocity of 50km/h to the east. How long will it take him to drive 150km/h on a straight highway?

Answer 1

please check the question, I think it is 150 km not hour. :)

@PRAXER Alex drives with an average velocity of 50km/h to the east. How long will it take him to drive 150km on a straight highway?
Sorry typo

Answer 4

his velocity is telling you that every hour, he will travel 50km. How many hours will it take to travel THREE TIMES THAT FAR?

Answer 5

It is just the distance,speed and time formula, which is

Speed=distance/time
=> time = distance /speed

plug the value of average velocity in place of speed and 150 km in place of distance. Since it is on a straight way, so, there is not much confusion.

Hope you will be able to do the rest of the calculation.

Answer 6

@praxer I was hoping you would help me with the calculation so I can do the other 3 I have on my own. My first time taking physics. :(

Answer 7

ya it is very simple just plug the values it will be time = distance /speed = 150/50=3hour

Answer 8

since distance is in Km and speed is in the Km / hour. Hence the time will be in hour.
