A conveyor belt carries supplies from the first floor to the second floor, which is 27 feet higher. The belt makes a 60° angle with the ground. How far do the supplies travel from one end of the conveyor belt to the other? Round your answer to the nearest foot. If the belt moves at 75 ft/min, how long, to the nearest tenth of a minute, does it take the supplies to move to the second floor?

47 ft; 38 min

31 ft; 0.4 min

38 ft; 23.3 min

16 ft; 1.1 min

**Reiny**, Friday, February 15, 2013 at 1:05pmYou are just looking for the hypotenuse of a right-angled triangle with height 27 and base angle of 60°

using fundamental trig ....

sin60° = 27/h, where h is the hypotenuse

h = 27/sin60 = 31.1769 ft

= 31 ft, 2 inches

time =distance/rate = 31.1769/75 = .416 minutes
