An airplane is asked to stay within a holding pattern near an airport. The function d(x)=60sin(.61x)+190 represents the distance d, in miles, that the airplane is from the airport at time x, in minutes. During the first 23 min after the plane enters the holding pattern, at what time x is the plane exactly 170 miles from the airport?

Question
