Answer:

45 miles

Explanation:

Speed = distance / time

Lets assume :

speed = x

Distance = D

Time = 3 hours

so in first case :

x = D / 3

D = 3x

Second case :

speed = x-5  ( he is traveling 5mph slower )

Distance = D ( Distance is same )

time = 4.5 hour

so,

x-5 = D / 4.5

D = 4.5(x-5)

since D is same in both cases.

3x = 4.5(x-5)

3x = 4.5x - 22.5

4.5x - 3x = 22.5

1.5x = 22.5

x = 22.5/1.5

x= 15

so speed is 15mph

D= 3x

so Distance = 3*15 = 45 Miles.

Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes ca
antoniya [11.8K]

The cooling rate of the substance is approximately 0.0732.

According to the statement, the Newton's law of cooling is defined by the following formula:

T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t} (1)

Where:

  • T_{s} - Final temperature, in degrees Celsius.
  • T_{o} - Initial temperature, in degrees Celsius.
  • t - Time, in minutes.
  • k - Cooling rate, in \frac{1}{min}.
  • T(t) - Current temperature, in degrees Celsius.

Please notice that substance reaches thermal equilibrium when T(t) = T_{s}, that is when temperature of the substance is equal to the temperature of surrounding air.

If we know that T_{o} = 80\,^{\circ}C, t = 15\,min, T_{s} = 50\,^{\circ}C and T(15) = 60\,^{\circ}C, then the cooling rate of the substance is:

60 = 50 + (80 - 50)\cdot e^{-15\cdot k}

\frac{60-50}{80-50}= e^{-15\cdot k}

\frac{1}{3} = e^{-15\cdot k}

k = -\frac{1}{15}\cdot \ln \frac{1}{3}

k \approx 0.0732

The cooling rate of the substance is approximately 0.0732.

<h3>What is Problem recognition?</h3>

Generally, Problem identification is the first step of the business buying process, and it occurs when someone within the firm identifies a problem or a need that can be addressed by purchasing a product or a service. This stage may also be referred to as "need recognition."

In conclusion, The process by which a customer becomes aware of a gap between their current position and the scenario that they want or consider to be ideal is known as problem recognition.
