#### Answer

The speed of the Concorde is $1502.2$ miles per hour.

#### Work Step by Step

This problem is asking for us to find the speed $A$ given the Mach number. We can plug in the value given for $A$ into the equation $M = \frac{A}{740}$ to find the speed of this aircraft. We plug in $2.03$ for $M$:
$$2.03 = \frac{A}{740}$$
To isolate $A$, we multiply both sides of the equation by $740$ to get rid of the fraction:
$$A = (2.03)(740)$$
We now multiply to get the value for $A$:
$A = 1502.2$ miles per hour
