A.) 10 divided by 40

B.) 40 divided by 10

C.) 40 times 10

D.) 40 plus 10

Answer 1

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 <===
