.. Eugene wants to ride his bike at least 40 miles today. The first hour wasmostly downhill, and he rode 13 miles. He has 3 more hours to ride.Write and solve an inequality to find how many miles per hour Eugeneneeds to ride to meet his goal.
[tex]\begin{gathered} x=miles\text{ per hour} \\ 3\text{ hours left} \\ 13+3x\leq40 \\ 13-13+3x\leq40-13 \\ 3x\leq27 \\ \frac{1}{3}\ast3x\leq\frac{27}{3} \\ x\leq9 \\ He\text{ needs to ride 9 miles per hour in order to meet his goal} \end{gathered}[/tex]
