I Believe it is 80% but I am not sure
Distance = speed rate x time
Speed rate = 120 miles per hour
Time = 3 hours
Replacing:
D = 120 mph x 3 h = 360 miles
Step by step:
GR-8 = 34x - 12
• move variable to left hand side
-34x + gr -8 = - 12
• change expression and move to right side
-34x = - 12 - gr - 8
• calculate sum
-34x = - 4 - gr
• divide both sides
X = 2/17 + 1/34gr
And there’s your answer :)
Given

The first 10 partial sums are as follows:


The rest of the partial sums can be obtained in similar way.
Answer:
i think its the 3rd option
