Question

A train cover 35 km in 25 min. What is the speed of the train in the km per hour?

Answer 1

GIVEN

Distance covered by a Train = 35km

Time Taken by it = 25min

Now, 1hr = 60min

=> 25min = 25/60hr = 5/12hrs

Time Taken = 5/12hrs

TO FIND :- Speed in kmph

SOLUTION

Speed (Km/hr) = Distance(Km)/Time(hr)

= 35 ÷ 5/12

= 35 × 12/5

= 7 × 12

= 84kmph

Hence the speed of the Train in is 84kmph (ANS)

Answer 2

$\large{ \bold{\fbox{ \fbox{Given :- \: }}}}$

$\to\bold{Distance = 35 \: Km } \\ \to\bold{Time = 25 \: Min = \frac{25}{60} \: Hr = 0.4 \: Hr \: \: }$

$\large{\bold{\fbox{ \fbox{To \: Find :- }}}}$

$\to\bold{Speed \: Of \: The \: Train \: In \: Km/Hr \: }$

$\large{ \bold{\fbox{ \fbox{Solution :- \: }}}}$

${ \bold{ \underline{We \: Know \: That \: , \: \: \: }}}$

$\fbox{\huge{ \bold{ \: Speed = \frac{Distance \: }{Time \: } \: \: }}}$

$\to\bold{Speed = \frac{35}{0.41} } \\ \\ \to\bold{Speed = 85.3 \: \: \: Km/Hr \: }$
