A plane flying with a constant speed of 150 km/h passes over a ground radar station at an altitude of 3 km and climbs at an angle of 30°. At what rate is the distance from the plane to the radar station increasing a minute later? (Round your answer to the nearest whole number.)

what I suppose to differentiate?

anonymous · Answer

Find X  = the rate of change of distance =speed

cos 30 = 150 / X

X = 150 / cos 30

Once you find X
divide it by 60 to get the rate of change a minute later
