Answer:
30 minutes.
Step-by-step explanation:
Are you sure po na yung speed 3 minutes lang ang nakasulat? Kasi usually po yung uniylt for speed is written in (unit)/(time unit) ex. meters/hour or mph. Baka yung speed po ang unit niya 3 meters per minute? If oo Ito po yung solusyon
Formula for Time = Distance ÷ Speed
Distance = 90 meters
Speed = 3meters per minute
90 ÷ 3 = 30
Time = 30 minutes.
