Evaluate how fast is it going

Reference no: EM13657236

At the Indianapolis 500, you can measure the speed of cars just by listening to the difference in pitch of the engine noise between receding and approaching cars. Assume the sound of a certain car drops by a factor of 1.90 as it goes by on the straight away. Evaluate how fast is it going? (Take the speed of sound to be 343 m/s.)
