The total distance traveled by the lioness is 60 m + 60 m + 120 m = 240 m. The total time taken is 15 s + 20 s + 25 s + 20 s = 80 s.
Average speed = total distance / total time = 240 m / 80 s = 3 m/s
Therefore, the answer is c) 4 m/s.
A lioness hunting antelope runs a distance of 60 m in 15 s. Then she stops to survey the herd
for 20 s. Next, she trots for 25 s over 60 m around the edges of the herd. Finally, the lioness
races after the antelope, traveling 120 m in 20 s. What is the average speed of the lioness?
a 80 m/s
b 12 m/s
c 4 m/s
d 0.5 m/s
