Question

Suppose a railroad rail is 2 kilometers and it expands on a hot day by 19 centimeters in length. Approximately how many meters would the center of the rail rise above the​ ground?

Answer 1

rail rise approximately 0.19 m above the ground

Explanation:

as we know that

1m=100cm

and 1cm=
`(1)/(100)` m

similarly

19cm=
`(19)/(100)`m

19cm=0.19m

rail rise approximately 0.19 m above the ground
