Question
A plane takes off from a nearby airfield and climbs at an angle of 25° to the horizontal, at 220km/h along its flight path for 45 minutes. how far does it go
Answers
Reiny
distance along flight path
= (3/4)(220) = 165 km
measured horizontally:
cos 25° = x/16
x = 165cos28
= 49.54 km
= (3/4)(220) = 165 km
measured horizontally:
cos 25° = x/16
x = 165cos28
= 49.54 km
