Answer:
5000 m equivalent to 5 Km
Explanation:
Average velocity =
so, Displacement =Average velocity × time
We should convert Km/h to m/s so Km/h ⇒
m/s, also convert time to second so, 20min ⇒(20* 60)seconds
Displacement = (15 ×
) × (20×60) =5000m OR 5Km
The molarity remains the same so the ratio does not change
