Answer:
[tex]5.26\dfrac{m}{s}[/tex]
Step-by-step explanation:
We need to know the total time in seconds, then converting the 4 minutes to seconds:
[tex]4\,min\dfrac{60\,s}{1\,min}=240\,s[/tex]
Now adding both quantities in seconds:
[tex]240\,s+45\,s=285\,s[/tex]
To find the unit rate we just need to divide the distance that Joel ran by the total time in seconds, then:
[tex]\dfrac{1500\,m}{285\,s}=5.26\dfrac{m}{s}[/tex]
Then each second Joer ran 5.26 meters.
