Question

Two cars start moving from the same point. One travels south at 60 mi/h and the other travels west at 50 mi/h. At what rate is the distance between the cars increasing 2 hours later? Round to the nearest hundredth.

Answer #1

Two cars start moving from the same point. One travels south at
56 mi/h and the other travels west at 42 mi/h. At what rate is the
distance between the cars increasing two hours later?
mi/h

Question 1:
Two cars start moving from the same point. one travels south
at 48 mi/h and the other travels west at 20 mi/h. At what rate is
the distance between the cars increasing two hours later?
Question 2:
A boat is pulled into a dock by a rope attached to the bow of
the boat and passing through a pulley on the dock that is 1 m
higher than the bow of the boat. If the rope is pulled...

7. Two cars start moving from the same point. One travels north
at speed of 15 mi/hand the other travels east at 20 mi/h. At what
rate is the distance between the cars increasing two hours
later?

Two cars start moving from the same point. One travels
south at 56 mi/hr and the other
travels west at 42 mil/hr. At what rate is the distance between the
cars increasing two hours later?
Step 1: Write all the rates in the problem (including the one you
are trying to find) as
derivatives.
--
Step 2: Identify the dependent variables in the derivatives. Find
an equation relating
the dependent variables in the derivatives. You will often need a
formula...

Two people start from the same point. One walks east at 9 mi/h
and the other walks northeast at 6 mi/h. How fast is the distance
between the people changing after 15 minutes? (Round your answer to
three decimal places.)

Two cars leave the same point at the same time. One travels east
at 50 mph, while the other travels north at 80 mph. How fast are
the cars moving away from each other after 2 hours

A car starts from a point at 2:00 p.m. and travels north at 40
mph. Another car starts from the same point at 3:00 p.m. and
travels west at 50 mph. After the second car has traveled 1 h, at
what rate is the distance between the two cars changing?

One car leaves an intersection traveling north at 48 mi/h.
Later, a second car leaves that same intersection traveling east at
90 mi/h. At what rate is the distance between the cars increasing
when the first car is 96 miles north of the intersection and the
second car is 72 miles east of the intersection?

Two cars travel in the same direction along a straight highway,
one at a constant speed of 55 mi/h and the other at 60 mi/h.
(a) Assuming they start at the same point, how much sooner does
the faster car arrive at a destination 14 mi away? min
(b) How far must the faster car travel before it has a 15-min
lead on the slower car? mi

Two cars are traveling on level terrain at 60 mi/h on a road
with a coefficient of adhesion of 0.8. The driver
of car 1 has a 2.5-s perception/reaction time and the driver of car
2 has a 2.1-s perception/reaction time.
Both cars are traveling side by side and the drivers are able to
stop their respective cars in the same distance
after first seeing a roadway obstacle (perception and reaction plus
vehicle stopping distance). If the braking
efficiency of...
