Question

Amanda can jog 18 miles in 5 hours. At this rate, how many miles can Amanda jog in 4 hours?

Answer 1

we know that

Amanda can jog $18$ miles in $5$ hours

so

by proportion

Find the number of miles that Amanda  can jog in $4$ hours

$\frac{18}{5} \frac{miles}{hours} =\frac{x}{4} \frac{miles}{hours} \\ \\5*x=18*4 \\ \\x=72/5 \\ \\ x=14.4\ miles$

therefore

the answer is

$14.4\ miles$

Answer 2

18 = x
