The equation that represents Runner #2 is t = 8.5d where t is time (in minutes) and d is distance in miles). If Runner #2 runs 2 miles, how many minutes will it take?

Runner #2's equation is an illustration of proportional equations

It will take runner #2 17 minutes to run 2 miles

Runner #2's equation is given as:

When runner #2 runs two miles, it means that:

d = 2

Substitute 2 for d in the given expression.

So, we have:

Multiply

Hence, it will take runner #2 17 minutes to run 2 miles

Step-by-step explanation:

Given the equation of the time t = 8.5d took by aa runner to ru n. If the runner ran 2 miles, to calculate the time take by the runner to run two miles, we will substitute d = 2 into equation and calculate t as shown;

t = 8.5d

t = 8.5(2)

t = 17.0 minutes

Hence it will take the runner 17minutes to run 2 miles.
