Answer:
14.5 hours
Explanation:
The relationship between speed, time and distance for a uniform motion is
[tex]v=\frac{d}{t}[/tex]
where
v is the speed
d is the distance
t is the time taken
Here we know:
v = 24.0 m/s is the average speed
[tex]d=1250 km = 1.25\cdot 10^6 m[/tex] is the distance
Solving the equation, we find the time taken:
[tex]t=\frac{d}{v}=\frac{1.25\cdot 10^6 m}{24.0 m/s}=52083 s[/tex]
And since
1 hour = 3600 s
The time in hours is
[tex]t=52083 s \cdot \frac{1}{3600 s}=14.5 h[/tex]
