Jamie took 2 hour and 30 minutes to reach the because 5:30-3:00=2hours and 30 minutes.Raul took 1 hour 30 minutes to reach state park because 4:30-3:00=1 hour and 30 minutes.Since they went in opposite directions you can add the time to get 4 hour.It would take 4 hours to go from the beach to state park.There speed was 60 miles per hour since 240/60=4/1 mph.

Given:
Jamie: house to beach = 3 pm to 5:30 pm = 2 hours and 30 minutes
Raul: house to state park  = 3 pm to 4:30 pm = 1 hour and 30 minutes

Distance of beach and state park = 240 mi
travel from beach to state park = 2 hours and 30 minutes + 1 hour and 30 minutes = 4 hours

speed = distance / time
s = 240 mi / 4 hours
s = 60 mi/hr

Their speed is 60 miles per hour.

Using chain rule, what is the derivative of arcsin(sin(x))
oee [108]
Chain rule:
if
y=y(u) and u=u(x)
The dy/dx=(dv/du)(du/dx)

In our case
y=arcsin(u)
u=sin(x)

dy/du=1/√(1-u²) = 1/√(1-sin²x)
du/dx=cos x

dy/dx=cos x /√(1-sin²x)

Answer: dy/dx=cos x /√(1-sin²x)
