Answer is 68.9 m/min.
Step-by-step explanation :-
Let's convert the units. To do this, we need to cancel the original units to get the units we want. We achieve this the following way :-
![2.57 (mi)/(hr) * (1069.34 \: m)/(1 \: mi) * (1 \: hr)/(60 \: min)](https://img.qammunity.org/2022/formulas/mathematics/college/ldqillx1shfpd43iairm305h6gyrsipbbm.png)
![=>68.9 \: (m)/(min)](https://img.qammunity.org/2022/formulas/mathematics/college/9er6g8gaptndoa1a11ojmr5gkdzl5ktuma.png)
Therefore, 2.57 mi/hr is the same as 68.9 m/min .
