Answer:
Option C.
Step-by-step explanation:
We need to translate each phrase and find the different expression.
"+" sign is used for sum, more and total.
Twice means two times of a number.
Let n be the unknown number.
Two more than a number = n+2
The total of n and 2 = n+2
Twice the number n = 2n
Sum of n and 2 = n+2
From the above expressions it is clear that only 2n is different from other.
Therefore, the correct option is C.

Answer:
<u>The correct answer is B. 40 mph</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Distance (d) the car traveled = 120 miles
Time (t) of the travel = 3 hours
2. What is the average rate of speed?
Rate of speed (r) = Distance (d) the car traveled/Time (t) of the travel
Replacing with the real values, we have:
Rate of speed (r) = 120/3 miles per hour
Rate of speed (r) = 40 miles per hour
<u>The correct answer is B. 40 mph</u>
