Answer :
Given,
Speed of the bus, S=80 km/hr
Distance of museum from the school, D=240 km
The speed is given by the formula,
[tex]S=\frac{D}{t}[/tex]Where t is the time taken to travel a distance of D
On rearranging the above equation, we get
[tex]t=\frac{D}{S}[/tex]Now, we substitute the value of speed and distance in the above equation to get the time required to travel from the school to the museum.
i.e.
[tex]t=\frac{240}{80}=3\text{ hr}[/tex]Therefore the time required to travel from the school to the museum is 3Hours
Hence the
