To solve this problem you must apply the proccedure shown below:
1. You need to apply the following formula:
[tex] speed=\frac{distance}{time} [/tex]
2. You have that the distance is [tex] 23 km [/tex] and the time is [tex] 41.4 min=0.69 hr [/tex]. Therefore, you only have to substitute values into the formula. So, you obtain:
[tex] speed=\frac{23km}{0.69hr}=33.33km/hr [/tex]
The answer is: [tex] 33.33km/hr [/tex]
