Kingda Ka in New Jersey is the tallest and fastest rollercoaster in the world. Riders travel at an average speed of 61 feet per second for 3118 feet. They reach a maximum speed of 187 feet per second. If x represents the total time that the roller coaster is in motion for each ride, write an expression to represent the situation. (Hint: Use the distance formula d=rt)

a negative exponent is translated as follows:

a^{-m} = \dfrac{1}{a^m}

so, we have

\left(5^{-1}+3^{-1}+2^{-1}\right)^{-1} = \left(\dfrac{1}{5}+\dfrac{1}{3}+\dfrac{1}{2}\right)^{-1} = \left(\dfrac{6+10+15}{30}\right)^{-1}=\left(\dfrac{31}{30}\right)^{-1}=\dfrac{30}{31}
