Luke: 2 miles in 40 minutes, 20 minutes a mile, (2/40 = 20 minutes a mile)
Luke's speed is 3 miles an hour (60minutes/20minutes a mile = 3miles).

Sally: 0.05 miles a minute, 60 minutes in an hour, 60 x 0.05 = 3 miles an hour. Or 0.05 miles a minute, 40 minutes walked, 40 x 0.05 = 2 miles walked.

There are a few other ways to show that they are accurate rates.

So yes, they are both correct rates.

–2|u| = –68<br> ill give 5 oints

german

The solution to the given equation –2|u| = –68 is u = 34, -34.

<h3>What is the solution to the equation?</h3>

Given the equation in the question;

–2|u| = –68

To find u, divide both sides by -2

–2|u| = –68

(–2|u|)/2 = (–68)/-2

|u| = 34

Remove the absolute value term, this create ± on the right side of the equation. ( |x| = ±x )

u = ±34

Hence,

u = 34, -34

Therefore the solution to the given equation –2|u| = –68 is u = 34, -34.

Jorge, sandra, danny, and valeria each mowed lawns after school and on the

Ronch [10]

Jorge mowed 18 lawns.

Let the number of lawns mowed by Jorge =x

So according to the question

Number of lawns mowed by sandra = x/3

Number of lawns mowed by Danny =x/2

Number of lawns mowed by Valeria =16

sum of total lawns mowed = lawns mowed by Jorge + lawns mowed by sandra + lawns mowed by Danny + lawns mowed by Valeria.

$x+\frac{x}{3} +\frac{x}{2} +16=49$

taking LCM as 6 and solving further we get

$\frac{6x+2x+3x+96}{6} =49$

By cross Multiplying we get

11x+96=294

11x=198

Solving further for x,

x=198/11

x=18

Therefore, the number of lawns mowed by Jorge is 18 .
