hello
to solve this question, we need to know the relationship between distance, time and velocity
according to mechanics, velocity is the rate of distance covered with time
[tex]\text{velocity = }\frac{dis\tan ce}{time}[/tex]in this question, we should get some data before we can proceed
velocity = 2500m/s
distance = 15400km
time = ?
note: we have our distance in km unit and not m (metre). We'll need to convert the distance from km to m so as to have a unified data
according to metric table.
1km = 1000m
15400km = x
cross multiply both sides and make x the subject of formula
[tex]\begin{gathered} 1\operatorname{km}\text{ = 1000m} \\ 15400\operatorname{km}\text{ = x} \\ \text{cross multiply and make x the subject of formula} \\ 1\text{ }\times\text{ x = 1000 }\times\text{ 15400} \\ x\text{ = 15400000} \\ \text{therefore, 15400km = 15400000m} \end{gathered}[/tex]now, we already established that velocity is the ratio between distance and time
[tex]\begin{gathered} \text{velocity = }\frac{dis\tan ce\text{ }}{time} \\ \frac{2500m}{s\text{ }}\text{ = }\frac{15400000}{time} \\ \text{time = }\frac{15400000}{2500} \\ \text{time = 6160s} \end{gathered}[/tex]it'll take exactly 6160 seconds for the satallite to travel at the rate of 2500m/s
