Q #1: If (D) is the distance traveled and (R) is the rate of travel, which of the following represents the relationship between D and R for the equation D=2R?
A. D is twice as much as R
B. R is twice as much as D
C. R is two than D
D. D is town more than R
Answer Explanation
Given the equation D=2R means that the get the value of D, multiply the value of R by 2. That is D is two times the value of R.

Q #2: Which of the following is 31% of 426?
A. 425.69
B. 132.06
C. 13.7
D. 0.07

Q #3: The force applied is directly proportional to the stretch of a coil. If a force of 132 Newtons stretches a coil 0.07 meters, what force would be needed to stretch a coil 0.1 meter? Round your answer to the nearest tenth.
A. 92.4 Newtons
B. 1885.7 Newtons
C. 188.6 Newtons
D. 136.0 Newtons
Answer Explanation
In direct proportion relation, we utilize the relationship as:
Variable∝
Variable 2Thus from the given case,
Force∝
stretchWe introduce a constant term, K to remove the sign of proportionality as
Force=K* stretch
Let’s find the value of K, using Force=132 N and stretch of 0.07 m
132 N=K*0.07 m
K=132 N/0.07 m=1885.7 N/m
Now substitute this value of K in the following equation
Force=1885.7 N/m * stretch
For a stretch of 0.1 m, the force needed is
Force=1885.7 N/m * 0.1 m=188.57 N=188.6 N
