clearly the angle is x (from directly ahead), where
sin(x) = 25/31
If it takes t hours, then
0.3^2 + (25t)^2 = (31t)^2
A zebra sees a lion 300 m to his right. The zebra starts running at 25 KpH straight ahead to get away. At this point the lion launches himself on an intercept course at the zebra at a speed of 31 KpH.
a. At what angle does the lion launch himself?
b. If both animals continue to travel straight, how long does it take the lion to catch the zebra?
