Thx to @calculista

Answer 2

we know that

`1\ mile=5,280\ feet`

`1\ hour=3,600\ sec`

1) convert miles per hour to feet per hour

`40\ miles/hour=40*5,280=211,200\ feet/hour`

2) convert feet per hour to feet per second

`211,200\ feet/hour=211,200/3,600=58.67 feet/sec`

Round to the nearest whole number------->
`59 feet/sec`

therefore

the answer is

`59 feet/sec`
