nlexa [21]

We can assume that B leaves Los Angeles not at noon but at 2pm Eastern Time, so 5 hours later than A leaves New York.

In 5 hours A covers 5*40=200 miles. So, A and B together should cover 3,000-200=2,800 miles.

Combined rate = 40 + 60 = 100 miles per hour.

To cover 2,800 miles they'll need 2,800/100=28 hours.

2pm Eastern Time on Monday + 28 hours = 6pm Eastern Time on Tuesday.

Answer: 6:00pm on Tuesday

Elyse uses 42 gallons of water in a 10-minute shower. Write and solve a prediction problem that uses this information

kvv77 [185]

Let

x-----> the time in minutes

y------> the number of gallons of water

we know that

the unit rates is equal to

$\frac{y}{x} = \frac{42}{10}=4.2\frac{gal}{min}$

the unit rate is equal to the slope of the linear equation

then

$y=4.2x$

Problem

1) How many gallons of water will Elyse use in three minutes in the shower?

For x=3 minutes

substitute in the equation above

$y=4.2x$

$y=4.2*3$

$y=12.6 gal$

the answer is

12.6 gal
