[tex]\large\bf\underline\red{Answer \: :- }[/tex]
Given :-
A train travels 3600km at speed 60km/hr.
To find :-
What is distance at speed 80km/hr.
Solution :-
We know that,
[tex]★ \: {\small{\underline{\boxed{\bf{\pink{Speed = \frac{Distance }{ Time} }}}}}} [/tex]
Putting the values by given question
[tex]⇢\sf{80 = \frac{distance}{60} } \\ [/tex]
[tex]⇢\sf{distance = 80 \times 60}[/tex]
[tex]\sf\pink{⇢Distance = 4800km} [/tex]
4800km covered in same time at speed of 80 km/hr.
Answer : (3) 4800km
