Lakelyn is training for a triathlon she is practising her swiming running and biking skills so far she can swim at a rate of 250 yards every 5 minutes she can run 6 miles an hour and bike 12 miles an hour write an equation to show how long it will take lakely to run 18 miles

The answer to the question is

It would take Lalelyn bout 3 hours to run the 18m miles, and it will take her

and x +y+z =18 where x, y, and z are the distannce covered swimming, running and bikinr respectifully

Step-by-step explanation:

To solve the question, we lisrt out the variables as follows

Swimming speed of Lakelyn = 250 yards every 5 minutes or 250×12 = 3000 yards/hour = 1.7 miles/hr

Running speed of Lakelyn = 6 miles/hour

Biking speed = 12 miles/hour

The duration it will take for Lakelyn to run 18 miles is given by

Timee taken to run 18 miles t = (Distance covered)/ (Speed of Lakelyn))

or t = D/S

Substituting the known values of such as

Running speed of Lakelyn = 6 miles/hour

From which we have the time taken  to run 18 miles = 18 miles /(6 miles/hour) = 3 hours

should the 18 miles form part of the triathlon then, we have

and x +y+z =18

Where x, y and z are the distance covered Swimming, Running and Biking respectively
