Cody hiked at an average speed of 1 mile per hour for 5 hours on saturday. he hiked an average speed of 2 miles per hour for 3 hours on sunday.
which explanation correctly tells how to calculate the total number of miles that cody hiked in two days?

a. step 1: multiply 1 × 5.
step 2: multiply 2 × 3.
step 3: add the two products.

b. step 1: multiply 1 × 5.
step 2: multiply 2 × 3.
step 3: subtract the two products.

c. step 1: divide 1 ÷ 5.
step 2: divide 2 ÷ 3.
step 3: add the two quotients.

d. step 1: divide 1 ÷ 5.
step 2: divide 2 ÷ 3.
step 3: subtract the two quotients.

  A. Step 1: Multiply 1 × 5.

  Step 2: Multiply 2 × 3.

  Step 3: Add the two products.

Step-by-step explanation:

The total number of miles hiked will be the sum of the numbers of miles hiked each day. Each day, the number of miles hiked can be computed by multiplying time by speed:

  distance = speed × time

So, the total number of miles hiked is ...

  total miles = miles on day 1 + miles on day 2 . . . . . (sum, not a difference—eliminates choice B)

  total miles = (speed on day 1)×(time on day 1) + (speed on day 2)×(time on day 2) . . . . . (sum of products—eliminates choices C and D)

Choice A correctly describes the computation.

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
