Question

The position of a diving bell is
−3/4 mile relative to sea level. The diving bell reached this position after dropping from sea level at a constant rate for  1 1/2
hours.

Answer 3

is it saying it to divide or multiply

Answer 4

):?

Answer 5

Answer 6

\[-\frac{ 3 }{ 4 }miles = \frac{ 3 }{ 2 }hours\]

Answer 7

All you have to do is find the factor that converts 3/2hours into 2/2hours, or 1 hour, multiply it by -3/4miles, and you have your answer

Answer 8

Do so by using the following equation

\[\frac{ 3 }{ 2 }x = \frac{ 2 }{ 2 }\]

Solve for x

Multiply both sides by 2/3 to cancel 3/2 on x (isolating it)

\[x = \frac{ 4 }{ 6 } \rightarrow x = \frac{ 2 }{ 3 }\]

Answer 9

Multiply 3/2hours by 2/3 and you get.... 6/6 hours, or 1 hour. Multiply -3/4 by 2/3 and you get...

\[\frac{ -3 }{ 4 } \times \frac{ 2 }{ 3 } = \frac{ -6 }{ 12 } = \frac{ -1 }{ 2 }\]

Answer 10

For every 1/4 of a mile down, it takes 1/2 of an hour

Answer 11

so the answer is - 1 1/8

Answer 12

am I right

Answer 14

Shadowwwww, answer lol

Answer 15

-6/12

Answer 16

Out of everything I just typed out, all you needed to do was read this "For every 1/4 of a mile down, it takes 1/2 of an hour"

Answer 17

Though I wished you had been following what I had said, so you could learn ._.

Answer 18

Look for what the question is asking, and review what I have provided you with.

Answer 19

ok - 6/12 was right?

Answer 20

Maybe you can remember the distance traveled 'd', is equal to the constant rate of traveling 'r' times the time traveled 't'

Distance equals rate times time.
d = r*t

Given the distance -3/4 mi, and the time 3/2 hrs...
\[\large \frac{ -3 }{ 4 }=v*\frac{ 3 }{ 2 }\]
\[\large v=-\frac{ 1 }{ 2 }\]

Answer 21

The rate the thing is moving is v=-1/2 mi/hr with respect to the sea level.
The overall equation is then..

d = (-1/2) * t

if they want time t=1 hr, then the distance traveled for that time is.
d=-1/2 * 1 = -1/2
