Question

In baseball, the equation E=9R/I a pitcher's earned run average E, where R is the number of earned runs the player allowed and I is the number of innings pitched. Last season, a pitcher had an earned run average of 2.80 and allowed 70 earned runs. How many innings did the pitcher pitch last season?

Answer 1

Answer:

The innings pitched last season is 225.

Step-by-step explanation:

Given that,

Earned run average = 2.80

Allowed earned run = 70

The given equation is

$E=\dfrac{9R}{I}$

We need to calculate the innings pitched last season

Using given equation

$E=\dfrac{9R}{I}$

$I=\dfrac{9R}{E}$

Where, E = earned run

R = allowed earned run

I = innings pitch

Put the value into the formula

$I=\dfrac{9\times70}{2.80}$

$I=225$

Hence, The innings pitched last season is 225.
