Jack and Jill start driving from the same location. Jack drives 30 miles south while Jill drives west. If Jack and Jill are 78 miles apart when they stop, how many miles west did Jill drive? Show all work in solving the problem.

72 mles

Step-by-step explanation:

For better understanding, I'll make use of an attachment.

From the attachment,

O represents the start point

--- Jack

-- Distance between them

Required

Find OA; Jack's distance

To do this, we make use of Pythagoras theorem

This gives:

Subtract 900 from both sides

Take square roots

Hence, Jill drove 72 miles

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
