Suppose you are driving along at a constant 98.1 km/h (i.e., 61 mi/h) and you experience a 1.00 s long, eyes-closed, giant sneeze. How many meters does the car travel while you are out of control?

As obvious as the question might be to some,
first you must convert the two pieces of information into the same units in order to easily use them....either convert 1 second into hours or 98.1 km/h into km/second.
I choose to convert the speed (98.1 km/h),
giving a value of .02725 km/s, or 27.25 meters per second.
Since the length of the sneeze was 1 second long, by multiplying this length of time by the speed of the car, we find the car traveled 27.25 meters in the time it took the person to sneeze.

Need to multiply 98.1 km/hour by 1,000 to get 98,100 meters/hour.
Now divide by 60 to make it meters per minute
Now divide by 60 to make it meters per second.
this number will tell you how many meters you travelled in your one second sneeze.

98.1 km/h means that you travel 98.1km in an hour
therefore you travel 98.1/(60*60)km per second.
So if you keep your eyes for 1s you will have tarvelled,
98.1*1000/3600 m =27.25 m

Everybody that answered 27.25 meters was correct. WOW!!!!!!That's a long sneeze. I mean the 1.00 second long part.

first convert km/h to m/s
(98.1 km/h) / (3600 s/h) = 0.02725 km/s (hours cancel out)
0.02725 km/s * (1000 m/km) = 27.25 m/s (km cancel out)
velocity = distance / time so.......
27.25 m/s = d / 1.00 s
27.25 m/s (1.00 s) = d
27.25 m = distance traveled during sneeze
