HELP ME GUYS PLZ I NEED HELP 15 POINTS ON THE LINE!! AND BRAINLIEST!!!!which expression calculates the speed in meters per secon
irakobra [83]

Answer:

Step-by-step explanation:

distance = rate * time.( d = rt).....rate is speed....but we are looking for rate, so let me rearrange this formula...... r = d / t

r = d / t

distance (d) = 40m

time (t) = 10 seconds

so the rate (speed) can be found thru division....

r = 40 / 10 = 4m per second

so 40 divided by 10 is ur answer <===
