To find the average speed of the lioness, we need to calculate the total distance traveled and the total time taken.
Total distance = 60 m (first run) + 60 m (trotting) + 120 m (final race) = 240 m
Total time = 15 s (first run) + 20 s (surveying) + 25 s (trotting) + 20 s (final race) = 80 s
Average speed = Total distance / Total time = 240 m / 80 s = 3 m/s
Therefore, the answer is 3 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?
80 m/s
12 m/s
4 m/s
