Velocity; how far will the car travel? (Read)

Question

A car traveling north at an average velocity of 65 km/hr. How far will it travel at 180 minutes? **Make sure to include all proper units and labels in final answer Given: Average velocity= 65 km/hr t= 3 hours (after you convert from 180 minutes) d= ???? Answer choices: (1) 195 m North (2) 21.7 km (3) 195 km North (4) 21.7 km North

Answer 1

d = vt

 

v = 65 km/hr

 

t = 180 min = 3 hrs

 

d = (65 km/hr)(3 hrs) = 195 km

 

The car was going North, so the final complete answer is 195 km North, which is choice (3).

Answer 2

Distance = Rate*Time Distance = (65km/hr)*(3hours) Since ( 1 hour is 60 minutes) Distance= 195km Since the problem mentions velocity and velocity is a vector quantity you will need to mention North in your answer.
