Sam

Step-by-step explanation:

Sam made a mistake when he said $10^2 -20$ . The steps should have been:

$2n^2-20=2(5)^2-20\\2(25)-20\\50-20=30$

You are supposed to square 5 first before multiplying 2. Sam multiplied by 2 first. The correct answer is 30.

An airplane files with a constant speed of 680 km/h. How far can it travel in 2 1/4 hours?

Mekhanik [1.2K]

$\frac{distance}{hour} =\frac{680km}{1 hour} = \frac{x}{2\frac{1}{4}}\\
\frac{680}{1} = \frac{x}{2\frac{1}{4}}\\
680*2\frac{1}{4}=1*x\\
1530=x$

The plane can travel 1530km in $2 \frac{1}{4}$ hours.
