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

`(1)/(3,600) (hour)/(seconds) =(x)/(57.1) (hours)/(seconds)\\ \\3,600*x=57.1\\\\ x=(57.1)/(3,600) \ hours`

step
`2`

Find the speed in miles per hour

we know that

The speed is equal to

`speed=(distance)/(time)`

we have

`distance= 1\ mile \\\\ time=(57.1)/(3,600) \ hours`

`speed= (1)/((57.1)/(3,600)) \\\\ speed=(3,600)/(57.1)`

`speed= 63.05(miles)/(hour)`

therefore

the answer is

The speed is equal to
`63.05(miles)/(hour)`
