Answer:
I'd say that it's a good start, but he is assuming that his rate of growth will remain the same.
Since there are relatively few people 6'10" tall, it's likely that his extrapolation is too high.
Maybe if he could study the growth rates and heights at various ages of people who did achieve 6'10" height, he would have a sounder basis for his theory.
1/4 of x students made the honor roll in the first quarter
1/4 of x plus 18 equals 105
1/4 x + 18 = 105
1/4 x + 18 - 18 = 105 - 18
1/4 x = 87
Reciprocal to isolate variable
4/1(1/4 x) = 87(4/1)
x = 348
There is a total of 348 students in 7th grade
2400 miles in .........4 hours
X miles in .................1 hour
X = 2400 multiply 1 divided 4
X = 600 miles per one hour
