Question

which units are used to measure both velocity and speed? select three options.
□ m/s
□ d/t
□ km/h
□ mph
□ m²

Explanation:

Speed and velocity both measure rate of motion (distance/time). Units must have length/time. m/s (meters per second), km/h (kilometers per hour), and mph (miles per hour) fit. d/t is a formula, not a unit; m² is area, not motion rate.

Answer:

m/s, km/h, mph
