Solve the application problems. State your answer in a sentence. A helicopter travels 12 miles in the same amount time it takes an airplane to travel 15 miles The rate of the airplane is 30 mph greater than the rate of the helicopter. Find the rate of the helicopter. Use the equation, time = distance/rate

Solution

Dear Student Thank you for using Chegg !! Distance travelled by helicopter In t time 12 miles Distance travelled by plane in t time 15 miles Let speed of helicopter be s miles/hr =>Speed of plane s+30 miles/hr Since time taken by plane and helicopter is same time= Distance / speed (12/s) = 15 / (s+30) 12 (s + 30) = 15s 12*30 3s s= 120 miles/ hr
