Verified Answer :

AL2006

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

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 \(63.05\frac{miles}{hour}\)
