🔍 Key Concepts

• Speed of sound in air in feet per second (use the value commonly given on your exam formula sheet) • Sound must travel from the ship to the cliff and back, so the measured time is for a round trip • Relationship between distance, speed, and time: ( \text{Distance} = \text{Speed} \times \text{Time} )

💭 Think About

• Is the 4 1/2 seconds the time for the sound to travel one way or to go to the cliff and return? How does that affect the time you should use in your distance calculation? • Once you calculate the distance in feet, how do you correctly convert that distance into yards? • Which answer choice is closest to your calculated distance after you account for the round-trip travel of the sound?

✅ Before You Answer

• Use the correct speed of sound in air value (in feet per second) that your exam expects—don’t confuse it with knots or mph. • Be sure to divide the total time by 2 to get the one‑way travel time before calculating the distance to the cliff. • After computing distance in feet, divide by 3 to convert to yards and compare with the options.
