Answer:

47 miles

Step-by-step explanation:

The formula for Mean = Sum of values/Number of values

Number of values is 6

From the above question, we are only given 5 values,

The 6th value is represent as= x

Hence,

60 miles + 66 miles+ 70 miles+ 60 miles+ 51 miles + x miles/6 = 59 miles

Cross Multiply

60 miles + 66 miles+ 70 miles+ 60 miles+ 51 miles + x miles = 6 × 59 miles

307 miles + x miles = 354 miles

x miles = 354 miles - 307 miles

x miles = 47 miles

Therefore, the number of miles he need to run on day 6 is 47 miles
