Answer:

Step-by-step explanation:

In baseball statistics, earned run average (ERA) is the average of earned runs given up by a pitcher per nine innings pitched (i.e. the traditional length of a game). It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine.
20runs/50 innings= 0.4 runs
0.4 runs • 9 innings= 3.6 run average
