Final answer:
To determine the average number of miles Ian would have to ride to meet his goal, we can use the equation 8 + 5M = 36.5 and solve for M.
Step-by-step explanation:
To determine the average number of miles Ian would have to ride to meet his goal, we can set up an equation using the information given.
Let M be the average number of miles Ian would have to ride to meet his goal.
Since Ian has already ridden 8 miles and wants to ride a total of 36.5 miles, the equation would be: 8 + 5M = 36.5.
To solve for M, we can subtract 8 from both sides of the equation and then divide by 5: M = (36.5 - 8) / 5.
M simplifies to: M = 7.3.
Therefore, the average number of miles Ian would have to ride to meet his goal is 7.3 miles.
