Qt A
The time needed to drive \(a\) miles at \(\frac{b}{a}\) miles per hour
\(\frac{b}{a}\) miles in 1 hour, then
\(a\) miles in how many hours??
\(\frac{a * a}{b}\)
\(\frac{a^2}{b}\)
Qt B
The time needed to drive \(\frac{b}{a}\) miles at \(b\) miles per hour
\(b\) miles in 1 hour, then
\(\frac{b}{a}\) miles in how many hours??
\(\frac{b * a}{b}\)
\(a\)
We do not know the exact values of a & b
Answer D

But My instructor told that we can pick up any random number for the easy calculation and i chose a =10, b = 5, i got answer as c. Whats wrong in this approach sir?
