You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.
90/60 = 1.5
90 minutes = 1.5 hours
speed = distance/time = (105 miles)/(1.5 hours) = 70 mph
Answer:
None of these (see below).
Step-by-step explanation:
y = m cos pt - n sin pt
Using the chain rule:
dy/dt = m * -sin pt * p - ( n * cos pt * p)
= -mp sin pt - np cos pt.
dy/dt^2 = -mp * -cos pt * p - (np * - sin pt * p)
= mp^2 cos pt + np^2 in pt.
