Answer:
72 kilometres per hour
Step-by-step explanation:
The formula for calculating speed is distance/time.
So to work this out you would convert 2 minutes into hours. You would divide 2 by 60 to convert it into hours. This is because the standard unit for speed with kilometres is kilometres per hour. Then you would divide 2.4 by that.
1)Divide 2 by 60:

2) Divide 2.4 by 0.0333333.
![2.4/0.0333333=72.00007](https://img.qammunity.org/2021/formulas/physics/college/l07elhuvh4lx5tnfzupm7mne0h3ps0ia6v.png)
3) Round it.
