you walk 95.0 m at a speed of 1.26 m/s and then run 95.0 m at a speed of 3.61 m/s. what is the average velocity?

• physics -

total time = 95/1.26 + 95/3.61

total distance = 95+95

average speed
= total distance/total time

• physics -

time = distance/speed( m / m/s = s)
avg velocity is

totaldistance/totaltime

so, that gives

(95.0+95.0)/(95.0/1.26 + 95.0/3.61)
