After robbing a bank in Dodge City, a robber gallops off at 13 miles/hour. 30 minutes later, the marshall leaves to pursue the robber at 15 miles/hour. How many hours does it take the marshall to catch up to the robber?

21

jk it's 20

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.

i think it will be 4feet long of what i comprehend
