A car travels 40 meters in 10 seconds. Calculate the cars speed . Variables: Formula: Solve for variable:Put in Numbers:Calculate answer:

distance equals rate multiplied by time

the distance can be any unit (miles/km/etc …) the resulting number is based on the other variables.

the speed, again this can be any unit but will determine or be based on the speed … if you travelled so many miles the rate is going to be how many miles in so much time … km will be km per second/hour/etc)

the length of time is the amount of time which passes at the current speed to result in the gained distance. if you travel at 1mph for 1 hour you will go 1 mile.

d = r(t)

your equation was 40 meters travelled in 10 seconds. we can place it in lime that and get meters per second

40 = r(10)
r = 40/10 = 4
the rate here is now meters per second

in the same respect if we wanted meters per minute … since we have10 seconds that is the same as (1/6) of a minute …
r = 40/(1/6)

that will give you the rate in meters per minute which will be the same as meters per second multiplied by 60 (since there are 60 seconds in a minute)

so 4(60) = 240 …
r = 40/(1/6) = 240 which is 240 meters a minute
