Answer to Question #15223 in Mechanics | Relativity for john
a group of bike riders took of 4.0 hour trip during the first 3.0 hours they traveled the total 50 km during the last hour they traveled 10 km what was the froup avarage speed?
The total distance traveled by rides is
D = 50[km] + 10[km] = 60 km.
The total time elapsed is T = 4.0 hours, so the average speed was
V = D/T = 60[km]/4.0[h] = 15 km/h.
