Answer:
5/3 hours (or) 1.67 hours
Explanation:
Given information,
→ Ethan took 1 hour to walk 3 miles.
Now we have to,
→ Find the duration to cover 5 miles.
Let us assume that,
→ Need duration = H
Forming the equation,
→ 3/1 = 5/H
Then the value of H will be,
→ 3/1 = 5/H
→ 5/H = 3/1
→ 5 = 3 × H
→ 3H = 5
→ H = 5/3
→ [ H ≈ 1.67 ]
Hence, the answer is 1.67.
