hypotenuse = 9.85
Their earnings would be the same after 4 hours
Let the number of hours be x, and the weekly earning be y
So, the given parameters are:
<u>Kimi</u>
So, the equation for Kimi's weekly earning is:
<u />
<u>Jordan</u>
So, the equation for Jordan's weekly earning is:
Equate both equations
Collect like terms
Divide both sides by 2
Hence, their earnings would be the same after 4 hours
