P(arrives on time given leaves on time)=
P(B | A)= P(B n A) / P(A)
= P(A n B) / P(A)
= 0.36 / 0.9

Use the formula h=16t2, where t is time in seconds and h is the distance in feet traveled by a free-falling body or object to so

aksik [14]

Answer:

The time required is 15.97 second.

Step-by-step explanation:

Consider the provided information.

A skywalk is 90 feet beyond the canyon's edge and is 4080 ft above the canyon floor.

First find the distance between skywalk and canyon floor by using Pythagorean theorem.

Distance between skywalk and canyon's edge = $\sqrt{4080^2+90^2}$

Distance between skywalk and canyon's edge = $4080.99$

Substitute h = 4080.99 in the provided formula.

$4080.99=16t^2$

$t^2=255.062$

$t=15.97$

Hence, the time required is 15.97 second.
