Answer:
600 seconds or equivalently 10 minutes
Explanation:
Use the formula for velocity, and solve for the unknown time (t), as follows:
[tex]v=\frac{d}{t} \\1.5 \frac{m}{s} =\frac{900m}{t\\}\\t*1.5 \frac{m}{s} =900m\\t=\frac{900}{1.5} s= 600 s[/tex]
Notice that all units are in the appropriate SI units, and therefore the answer for time comes in seconds.
600 seconds = 10 minutes
