Question

An airplane can ascend at a rate of 54 1/2 meters in 2/3 of a second. How many meters can the airplane ascend in one second?

Answer 1

Answer:

The airplane ascends $81\,\frac{3}{4}$ meters in one second.

Step-by-step explanation:

Given that the airplane ascends $54\,\frac{1}{2}$ ($\frac{109}{2}$) meters in $\frac{2}{3}$ seconds, we calculate the ascent rate of the airplane by simple rule of three:

$x = \frac{\frac{109}{2}\,m }{\frac{2}{3}\,s } \times 1\,s$

$x = \frac{327}{4}\,m$

$x = 81\,\frac{3}{4}\,m$

The airplane ascends $81\,\frac{3}{4}$ meters in one second.
