  1. Jun 29, 2014 #1
    How do I find time when I already have final velocity, initial velocity, acceleration and distance?

    It depends, is the acceleration constant?

    Do you have any ideas how you might find the time?

    What is the definition of acceleration?

    Here's the question, Me and my friend drove 50 km. I travel at 90 km/hr, my friend traveled at 95 km/hr. How long will my friend wait for me at the end of the trip?

    If you drove for 1 hour, how far would you travel? What about your friend?

    What is the formula for calculating speed if you know distance traveled and the time it took?

    An interesting idea is to convert each into hours per km, then just *50.
