a camel walks for 450 meters then hops on a bicycle and rides for 100 meters riding with a speed of 25 m/s in the same direction the average speed of the camel for the entire trip is 7 m/s what speed did the camel walk

6.03 m/s

Explanation:

Average speed = total distance traveled/total time taken

7 = 450 + 100/total time

total time = 550/7 = 78.57 s

Speed of camel on the bicycle = distance/time

25 = 100/time

time = 100/25 = 4 s

Total time = 78.57 s

Time spent riding bicycle = 4 s

Time spent walking = total time - time spent riding bicycle

                                  = 78.57 - 4 = 74.57 s

Speed of walking = distance walked/time spent walking

                             = 450/74.57

                                 = 6.03 m/s
