Let x be the time it takes for the trip to be completed given that the speed is y.
When the time is 30 minutes (equal to 0.5 hour) shorter than x, the speed is 8 mph more than the original speed.
The equations that would best represent the given conditions are:
(1) 120 = (x)(y)
(2) 120 = (x - 0.5)(y + 8)
Simplifying,
y = 120/x
Substitute:
120 = (x - 0.5)(120/x + 8)
The value of x from the equation is 3. Thus, if I go with the usual speed, the time it will take me to finish the trip is approximately 3 hours.
C. Figure 11 and figure 1v are both compounds
Answer:
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
Physics is explicitly involved in studying <span>the motion of a spacecraft under gravitational influence. Thus the answer is C.
Physic focuses more on the measurement, gravity, distances, acceleration and motion. THough all the choices are sciences but the C. is the topic that physics is involved.</span>
