Please help me A circular running track is 1/4 mile long. Elena runs on this track, completing each lap in 1/20 of an hour.

How many minutes does it take Elena to run one mile?

How many miles does Elena run in one hour?

ahm,nandito nato sa but I think dimo nakita kaya heto nag copy nalang ako

Step-by-step explanation:

Elena's running speed is 5 miles/hour

Explanation:

The speed is defined as the covered distance per unit time

In the problem, we have:

The distance covered is the length (circumference) of the circular track which is given as \frac{1}{4}

of a mile.

We are also given that she completes each lap (she completes \frac{1}{4}

4

1

of a mile) in \frac{1}{20}

20

1

of an hour

To get her speed, we will divide the distance covered by the time taken to cover this distance

This is done as follows:

speed = \frac{\frac{1}{4} }{\frac{1}{20} } = 5

=5 miles/hour

This means that:

Elena can run 5 miles each hour

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

y -5 = (-1/4)(x + 8)
