Answer:
21.45 mi
Step-by-step explanation:
Distance = speed × time
The time it takes the lion is:
13.75 mi = 50 mi/hr × t
t = 0.275 hr
The distance ran by the cheetah in that time is:
d = 78 mi/hr × 0.275 hr
d = 21.45 mi
5/100 * 4 = 20/100 reduces to 1/5
The square root of 6 is 2.449... and that is closest to 3
