The answer is [tex]\frac{20}{3}[/tex]
According to the question,
The marching band begin at the 50 yard line a football field and march perpendicular to the 40 yard line.
hence,
So when the tuba players travels 18 inches with each marching pace , the paces are:
[tex]\frac{50+30+40}{18} = \frac{20}{3}[/tex]
So , the answer is [tex]\frac{20}{3}[/tex] paces.
Here, Distance divided by speed equal steps.
