1520

Explanation:

Step1: Identify the formula

To find the speed in MPH, we use the conversion factor: Speed (MPH) = Mach number × 760 MPH.

Step2: Substitute the values

Given Mach number is 2.1, so we calculate \( 2.1 \times 760 \).

Step3: Perform the multiplication

\( 2.1 \times 760 = 1596 \)

Answer:

1596
