Joanne and karen run the 5000 feet from their house to the park. karen sets off first, but runs 2.5 feet per minute slower than joanne. the girls reach the park at the same time. if karen takes 15 minutes to run to the park, how long does joanne take?

It will take Joanna nearly the same time as Karen to run the park and time taken is 15 min and 7 seconds.

Step-by-step explanation:

Let the time taken by Joanne be 'x' minutes.

Given:

Total distance traveled by both is,

Speed of Karen is 2.5 feet per minute slower than Joanne's.

Time taken by Karen is,

Now, speed of Karen is given as:

Now, as per question,

Speed of Karen = Speed of Joanne - 2.5

∴ Speed of Joanne = Speed of Karen + 2.5

Now, we have speed of Joanne and distance traveled by Joanne. Therefore, time taken by Joanne is given as:

Therefore, it will take Joanna nearly the same time to run the park and time taken is 15 min and 7 seconds.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
