Answer:

The average speed is 16 km/hr.

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 =
(1)/(60) hours

15 minute =
(15)/(60) hours

15 minute = 0.25 hours

The speed formula is given by,

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

$\text{Speed}=(4)/(0.25)$

$\text{Speed}=16$

Therefore, The average speed is 16 km/hr.
