well, a stopwatch and a speedometer will do. Get the speed and time of going through this distance, and multiply by them, you will get the number.
yes you do need to measure with a stopwatch try expierment
One person holds the gun and the stopwatch. The other person walks away, unrolling the tape measure ast they go - and stops at an agreed distance. The first person fires the gun - and starts the stopwatch. The second person signals when they hear the shot - and the stopwatch is halted. Divide the time taken for the shot to be heard by the measured distance - and you have the speed of sound.
to measure time
A stopwatch or a measuring tape can be used to measure the speed of a snail. You would time how long it takes the snail to travel a specific distance, or measure the distance the snail travels in a set amount of time.
-- Mark its location as you start your stopwatch. -- After some time has passed, mark its location again as you stop the stopwatch. -- Measure the distance between the two marks. -- Read the elapsed time on the stopwatch. -- Divide (distance traveled)/(time to travel the distance) . The quotient is the object's average speed during the interval. The shorter the measurement interval, the closer the result is to an instantaneous speed.

a stopwatch
A stopwatch is a timekeeping device used to measure the duration of an event. The least count of a mechanical stopwatch typically used in laboratories is 0.1 seconds, meaning it can measure time intervals in increments of 0.1 seconds.
A chronograph is similar to a stopwatch. Not only does it function as a sort of stopwatch, it can also calculate speed and distance.
