Lakelyn is training for a triathlon. She is practicing her swimming, 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 Lakelyn to run 18 miles.

d = 6t

Time required will be 3 hours.

Step-by-step explanation:

Lakelyn can  swim at a rate of 250 yards every 5 minutes. She can run 6 miles an hour and bike 12 miles an hour.

Therefore, her running speed is 6 miles per hour.

Therefore, the function that models the running distance (d) in miles and the time span of running (t) in hours is given by

d = 6t (1)

Using the above equation we can calculate the time required by her to run 18 miles.

So, 18 = 6t

⇒ t = 3 hours. (Answer)

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
