My friend sets out walking at a speed of $3$ miles per hour. I set out behind her $5$ minutes later at $4$ miles per hour. When

Answer: The answer is 0.25 miles.

Step-by-step explanation: Given that my friend started walking at a speed of 3 miles per hour and I started 5 minutes after him at a speed of 4 miles per hour. We need to find the number of miles my friend travelled when I started walking.

Since I started 5 minutes after than my friend, so we are to find the distance travelled by my friend in 5 minutes.

In 1 hour, i.e., 60 minutes, distance travelled by my friend = 3 miles.

In 1 minute, distance travelled by my friend is

$\dfrac{3}{60}=\dfrac{1}{20}~\textup{miles}.$

Therefore, distance travelled by my friend in 5 minutes will be

$\dfrac{1}{20}\times 5=\dfrac{1}{4}=0.25~\textup{miles}.$

Thus, the answer is 0.25 miles.

Please help me I’m stuck

Gre4nikov [31]

Answer:

$x = 3.7$

Step-by-step explanation:

We can find the side of the hypotenuse by applying pythagorean theorem.

${5}^{2} + {5}^{2} = {x}^{2}$

$25 + 25 = {x}^{2}$

$50 = {x}^{2}$

$x = 5 \sqrt{2}$

Now we can apply pythagorean theorem on the other triangle

$(5 \sqrt{2} ) {}^{2} + {x}^{2} = {8}^{2}$

$50 + {x}^{2} = 64$

${x}^{2} = 14$

$x = \sqrt{14}$

$x = 3.7$
