The output must be as precise as possible hence distance and time will be float

If it's as precise as possible then you shouldn't float the distance, as it will be calculated at exactly 1320 feet

So you're saying, both should be in float?

That's what I think it should be, if the distance is a float, the user can put in partial feet to be more precise, otherwise they would have to round up/down.

At what point would an integer not be used? if the output should be as precise as possible? i would assume integers are used as rounded off numbers are a lot more precise with regards to the use of decimals?? looking for help.. i used both type floats

I would use both floats as the question doesn't state whether we measure our avg speed over whole lap.

From my understanding the length of the track will never change from the listed 1320 ft. so assigning the input as an "int' is more than sufficient. Assigning the input as a float would be redundant given the unchanging size of the track. With that in mind we then simply need to assign time as a "float" input. Different cars will be able to finish at different speeds.

Even if the distance of track remains same, we're trying here to take it from user. If he provides input as 1320.00, the program would fail. So from my experience it must be floats in both blanks.

it seems that the input for the distance should also be a float as a very precise input would get an error.

Both should be of type 'float' to ensure maximum precision;first answer is incorrect.
