Answer:
The answer to the question is
It would take Lalelyn bout 3 hours to run the 18m miles, and it will take her
[tex]\frac{x}{1.7} +\frac{y}{6} +\frac{z}{12} = t[/tex] 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
[tex]\frac{x}{1.7} +\frac{y}{6} +\frac{z}{12} = t[/tex] and x +y+z =18
Where x, y and z are the distance covered Swimming, Running and Biking respectively
Answer:
Step-by-step explanation:
We know that Lakelyn can run - 6 milles per hour. The question only needs to us for solve how long will it take lekelyn to run 18 miles. We don't need to do nothing with the rest of the data:
swiming - 250 yards every 5 minutes
biking skills - 12 miles per hour
When we separate the only data we need:
6 milles x hour
18 miles x ?
In 3 hours she'll run 18 miles. We only have to use a three rule for getting the result. First we multiply the 18 miles by 1 hour and the divide it by 6 miles.
