Question

Numerical
A train covers a distance of 820km with a speed of 80km/h. How long does it take to finish the journey??​

Answer 1

Provided that:

• Distance = 820 km
• Speed = 80 km/h

To calculate:

• The time taken

Solution: The train take 10.25 hours to finish the journey.

Using concept:

• Formula to calculate time

Using formula:

• ${\small{\underline{\boxed{\sf{Time \: = \dfrac{Distance}{Speed}}}}}}$

Required solution:

$:\implies \sf Time \: = \dfrac{Distance}{Speed} \\ \\ :\implies \sf Time \: = \dfrac{820}{80} \\ \\ :\implies \sf Time \: = \dfrac{82\not{0}}{8\not{0}} \\ \\ :\implies \sf Time \: = \dfrac{82}{8} \\ \\ :\implies \sf Time \: = \dfrac{\not{8}\not{2}}{\not{8}} \\ \\ :\implies \sf Time \: = \dfrac{41}{4} \\ \\ :\implies \sf Time \: = \dfrac{\not{4}\not{1}}{\not{4}} \\ \\ :\implies \sf Time \: = 10.25 \: hours$

Answer 2

Answer:-

• Distance=820km
• Speed=80km/h

We know that

$\boxed{\sf Time=\dfrac{Distance}{Speed}}$

$\\ \rm\longmapsto Time=\dfrac{820}{80}$

$\\ \rm\longmapsto Time=\dfrac{82}{8}$

$\\ \rm\longmapsto Time=10.25h$

$\\ \qquad\underline{\boxed{\bf{\therefore Time =10.25hour.}}}$
