Answer:

Step-by-step explanation:
We need to find the distance between the points (5, 2) and (1, 9). In order to do this, we will use something called the distance formula. The distance formula is written as follows:

Now we need to plug in our points which we have given in the form (x, y):

Next, perform the operation of subtraction inside the parentheses to simplify:

The exponent is the next step in the order of operations, so square 4 and -7:

Finally, add 16 to 49:

The square root of 65 cannot be simplified further, but an approximation can be made.

Calculate the circumference of the two semi circles, which equals a full circle. Then add the two sides of the track.
Circumference is pi x diameter = 3.14 x 22.8 = 71.592, so, you would need to add 71.592 + 49.2 + 49.2 = 169.992 meters, and that would be the length of one lap of the track.
Answer:
35 seconds
Step-by-step explanation:
if you simply minus 7 seconds from max 42 second time you get 35 seconds.
