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

The innings pitched last season is 225.

Explanation:

Given that,

Earned run average = 2.80

Allowed earned run = 70

The given equation is

`E=(9R)/(I)`

We need to calculate the innings pitched last season

Using given equation

`E=(9R)/(I)`

`I=(9R)/(E)`

Where, E = earned run

R = allowed earned run

I = innings pitch

Put the value into the formula

`I=(9*70)/(2.80)`

`I=225`

Hence, The innings pitched last season is 225.
