1. The problem statement, all variables and given/known data

Compute your average velocity in the following two cases: (a) You walk 59.5 m at a speed of 2.16 m/s and then run 59.5 m at a speed of 4.01 m/s along a straight track. (b) You walk for 1.00 min at a speed of 2.16 m/s and then run for 1.91 min at 4.01 m/s along a straight track.

2. Relevant equations

i have vavg = delta x/ delta t

but there is no time.. in the first part of the problem..

3. The attempt at a solution

i'm too confused :(

Average speed = total distance/total time

total time = time of first leg of journey + time of second leg of journey

time of first leg of journey = distance of first leg/speed of first leg

time of second leg = distance of second leg/speed of second leg

Got it?

Yes there is no time given. Can you find the appropriate times? How many seconds does it take you to travel 59.5 m if for every second that goes by you move 2.16 meters? Same approach for the second leg of the trip in question (a).
