[SOLVED] Another simple velocity question. "Juanita left on a walk 45 min ago. She is travelling at 4.5 km/h. How fast must you travel to catch up to her in 1.0h"? Juanita t=45 min v=4.5 km/h d=vt = (4.5km/h)(0.75h) = 3.375 km Me - v=d/t = (3.375km)/1.0h = 3.4 km/h I must travel at 3.4 km/h to catch up to her in 1 hour. Correct?
