Question

A submarine began at sea level and descended toward the ocean floor at a rate of −0.015 km per minute. Its final depth was −0.3675 km. Estimate how long it took the submarine to reach its final depth by rounding the dividend and divisor to the nearest hundredth.
Estimate of the dividend:



Estimate of the divisor:



Estimate of the quotient:

Answer 1

Answer:

The time  it took the submarine to reach its final depth is 24.5 min

Step-by-step explanation:

We are given

speed of submarine is -0.015 k/min

so,

$v=-0.015km/min$

Its final depth was −0.3675 km

so,

$d=-0.3675km$

we have to find time

we can use formula

$t=\frac{d}{v}$

now, we can plug values

$t=\frac{-0.3675}{-0.015}min$

$t=24.5min$

So,

Dividend is -0.3675

Divisor is -0.015

Quotient is 24.5

So,

The time  it took the submarine to reach its final depth is 24.5 min

Answer 2

Answer:

Estimate of the dividend: -0.37

Estimate of the divisor: -0.02

Estimate of the quotient: 18.5

Step-by-step explanation:

i took the test and got them all right they should be all right.

hope u have a nice day:)
