If a 1 HP motor at 120 V draws 6.21 A, then a 1.5 HP motor at 120 V would draw approximately between 9 and 10 A.

Explanation:
At a fixed supply voltage, a motor’s current scales with the input power it needs. Power in watts is V × I, so if a 1 HP motor at 120 V draws 6.21 A, that’s about 120 × 6.21 ≈ 745 W, which matches 1 HP (roughly 746 W). A 1.5 HP motor would require about 1.5 × 746 ≈ 1119 W. With the same 120 V supply, the current would be I ≈ 1119 / 120 ≈ 9.3 A, which falls between 9 and 10 A. Therefore the best answer is the range between 9 and 10 A.
