Question

Seth traveled 1 mile in 57.1 second how fast did he go in miles per hour

Answer 1

(1mile/57.1 sec) x (3,600 sec/hour) = 1 x 3600/57.1 = 63.05 mile/hour (rounded)

Answer 2

we know that

Seth traveled $1$ mile in $57.1$second

step $1$

convert $57.1$ second to hour

$1$ hour is equal to $3,600\sec$

by proportion

$\frac{1}{3,600} \frac{hour}{seconds} =\frac{x}{57.1} \frac{hours}{seconds}\\ \\3,600*x=57.1\\\\ x=\frac{57.1}{3,600} \ hours$

step $2$

Find the speed in miles per hour

we know that

The speed is equal to

$speed=\frac{distance}{time}$

we have

$distance= 1\ mile \\\\ time=\frac{57.1}{3,600} \ hours$

$speed= \frac{1}{\frac{57.1}{3,600}} \\\\ speed=\frac{3,600}{57.1}$

$speed= 63.05\frac{miles}{hour}$

therefore

the answer is

The speed is equal to $63.05\frac{miles}{hour}$
