1. Assign labels to the parts of the verbal model

Question

A metronome is a device similar to a clock and is used to maintain the temp of a musical piece. Suppose one particular piece has 180 measures with 3 beats per measure and a metronome marking of 80 beats per minute. Determine the length (in minutes) of the musical piece by using the following verbal model.

Metronome marking * Length of musical piece = Number of measure in musical piece * number of beats per measure

Answer 1

The translation of this problem into math is

80L=180*3

and L = 27/4=6 3/4 minutes

Notice the units in the equation

Beats/min * minutes = beats/measure * measures
