Response:
55 mph. All options are incorrect.
Detailed explanation:
When speed changes inversely with the time taken, it can be expressed as v ∝ 1/t, where:
v represents speed,
t refers to the time taken.
This leads to;
v = k/t, with k being a constant of proportionality.
Given that Kris takes 5 hours traveling at 55 mph, we replace v with 55 mph and t with 5 hours in the equation to find k as follows:
55 = k/5
Cross-multiplying yields:
k = 55 * 5
k = 275
To determine the speed Martin needs to drive for 5 hours, we substitute k = 275 and t = 5 back into the original equation v = k/t as follows:
v = 275/5
v = 55 mph
Thus, we conclude that in order to travel for 5 hours, Martin must also drive at 55 mph.
This issue involves a basic
dimensional analysis. We are required to express the rate of 0.992 atm/m in the unit of atm/km.
In straightforward terms, dimensional analysis means converting a measurement into a different unit using conversion factors.
For this case, the necessary steps are:

We observe that 1000 meters = 1 kilometer was used as the conversion factor to change atm/m into atm/km. Consequently, we conclude with the answer
992 atm/km.
Answer:

Step-by-step explanation:
The equation provided is:
d = 5x + 10xf
We need to isolate x from this equation.
Factoring out x from the right side gives us,
d=x(5+10f)
To find x, divide both sides by (5+10f),

Thus, this represents the sought value for x.
