Respuesta :
Answer: [tex]\dfrac{\text{d}}{\text{t}}[/tex] miles per minute
Step-by-step explanation:
We know that the formula to find speed is given by :-
[tex]\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}[/tex]
Given : Jimmy ran m miles in t minutes.
i.e. Expression for Distance = m
Expression for Time = t
Then Jimmy's speed is given by :-
[tex]\text{Speed}=\dfrac{\text{d}}{\text{t}}[/tex]
Hence, [tex]\text{Jimmy's Speed}=\dfrac{\text{d}}{\text{t}}[/tex] miles per minute.
