Answer:

25.92 foot strides

Step-by-step explanation:

The man will take 120/5 = 24 five foot stride to cover the initial 120 foot advantage of the child.

Within this time, the child would have covered an additional 24/5 x 2 = 9.6 extra foot stride.

Within this 9.6 food stride of the child, the man will have to take an additional 9.6/5= 1.96 strides.

Total foot stride by the man will be 24 + 1.96 = 25.92 foot strides.

How would I work this out

Answer:

10.1

Step-by-step explanation:

You can find the length of XY by first finding YZ using the Pythagorean theorem. Then subtract the length from 15 for the length of the other triangle. Use the Pythagorean theorem again to find XY.

The Pythagorean theorem is used for all right triangles and is the formula $a^2 + b^2 = c^2$ . Here a = 4, b is unknown and c = 7.

So $4^2 + b^2 = 7^2\\16 + b^2 = 49\\b^2 = 33\\b = \sqrt{33} =5.75$

Subtract 5.75 from 15.

15 - 5.75 = 9.25.

Repeat the Pythagorean Theorem again with a = 4, b = 9.25 and c is unknown. Solve for c. This is XY.

$4^2 + 9.25^2 = c^2\\16 + 85.56 = c^2\\101.6 = c^2\\10.1 = c$
