Answer:
The average speed is 16 km/hr.
Step-by-step explanation:
Given : It takes Francisco 15 minutes to ride his bike 4 km, which is the distance from home to school.
To find : What is his average speed?
Solution :
Distance covered from home to school is 4 km.
Time taken by bike to cover the distance is 15 minutes.
Converting minutes into hour,
1 hour = 60 minutes
1 minute = [tex]\frac{1}{60}[/tex] hours
15 minute = [tex]\frac{15}{60}[/tex] hours
15 minute = 0.25 hours
The speed formula is given by,
[tex]\text{Speed}=\frac{\text{Distance}}{\text{Time}}[/tex]
[tex]\text{Speed}=\frac{4}{0.25}[/tex]
[tex]\text{Speed}=16[/tex]
Therefore, The average speed is 16 km/hr.
