For this case we have both characters travel the same distance, then:
SB: Represents the average speed of SpongeBob
P: Represents Patrick's average speed
According to the data we have to:
[tex]SB = 14.88 \frac {km} {h} = 14.88 \frac {km} {h} * \frac {1} {60} \frac {h} {min} = \frac {14.88} {60} \frac { km} {min}[/tex]
If Patrick travels the same distance but with 4 minutes slower we have:
[tex]P = \frac {14.88} {60 + 4} \frac {km} {min}[/tex]
[tex]P = 0.2325 \frac {km} {min} * \frac {60} {1} \frac {min} {h} = 13.95 \frac {km} {h}[/tex]
Answer:
[tex]13.95 \frac {km} {h}[/tex]
