Answer:

X=2.5 min

Y=262.5 m

Step-by-step explanation:

Let x be the time ( in minutes ) Sam will take to catch Leo .

We know that : Distance = Speed x Time

Speed of Leo = 65 meters per minute

Speed of Sam = 105 meters per minute

According to the given situation, we have

Distance covered by Leo = (100 +65 x ) meters

Distance covered by Sam = 105 x meters

Sam will catch Leo when distance covered by Leo would be equal to  distance covered by Sam.  

 [ Subtract 65 x from both sides ]

x=2.5    [Divide both sides by 40]

therefore Sam will catch up Leo after 2.5 minutes.

ΔABC was dilated from point A to get ΔADE. Find the length of AD given a scale factor of 4.
rewona [7]

Since triangle ADE is similar to triangle ABC and the scale factor is 2, the following relation must be fulfilled:

\frac{AD}{AB}=4

The, by substituting the given information, we have

\begin{gathered} \frac{6x-8}{x+2}=4 \\  \end{gathered}

By multiplying both sides by x+2, we get

6x-8=4(x+2)

which gives

6x-8=4x+8

Then, by subtracting 4x to both sides, we have

2x-8=8

and by adding 8 to both sides, we obtain

2x=16

then, x is given by

x=\frac{16}{2}=8

Then, by substitutn
