Question

A train takes 10 hour to reach a destination if travel at a speed 65 km per hour what should we eat speed to reach the destination in 13 hours

Answer 1

Answer:

Given :

Time taken by the bus to reach a destination by travelling with a speed of 65 km/h is 10 hours

Time Taken by the bus to complete the same journey with some particular speed is 13 hours

To Find :

Speed of the bus when the bus takes 13 hours to complete the same journey

Solution :

$\Large\underline{\bf{\green{Case-I:}}}$

Speed of the bus = 65 km/hr

Time taken = 10 hours

Now , The Distance travelled by the bus is given by ,

$\begin{gathered} \\ \star \: {\boxed{\sf{\purple{distance = speed \times time}}}} \\ \end{gathered} </p><p>⋆$

distance=speed×time

Substituting the values ,

$\begin{gathered} \\ : \implies \sf \: d = 65 \: km {hr}^{ - 1} \times 10 \: h \\ \\ \end{gathered} </p><p>:⟹d=65kmhr </p><p>−1</p><p> ×10h$

$\begin{gathered} \\ : \implies \sf \: d = 65 \: km \times 10 \\ \\ \end{gathered} </p><p>:⟹d=65km×10$

$\begin{gathered} \\ : \implies{\boxed{\red{\sf{ \: d = 650 \: km}}}} \: \\ \\ \end{gathered} </p><p>:⟹$

d=650km

The distance travelled by the bus is 650 km.

\Large\underline{\bf{\green{Case-II:}}}

Time taken by the bus to complete the same journey = 13 hours

Distance = 650 km (Since it is the same journey)

Now , Applying the relation between Distance , Speed and time . We get ;

\begin{gathered} \\ : \implies \sf \: 650 \: km = s \times 13 \: h \\ \\ \end{gathered}

:⟹650km=s×13h

\begin{gathered} \\ : \implies \sf \: s = \frac{650 \: km}{13 \: h} \\ \\ \end{gathered}

:⟹s=

13h

650km

\begin{gathered} \\ : \implies{\boxed{\pink{\sf {\: s = 50 \: km {hr}^{ - 1} }}}} \: \bigstar \\ \\ \end{gathered}

:⟹

s=50kmhr

★

Hence , The speed of the bus when it completes the same journey within 13 hours is 50 km/hr

Answer 2

Answer:

For thhe train to arrive at its location in 13 hours, it must move at a pace of 50 km/h.

Step-by-step explanation:

If a train travels 65 kilometres per hour for 10 hours in order to reach its location, the distance travelled can be computed as follows:

Distance is determined by multiplying time and speed.

Mileage = 10 hours at 65 km/h.

≈ 650 kilometres away

The following calculation can be used to determine the train's required speed to get to the same location in 13 hours:

Speed = Distance / Time

where Duration is 13 hours and Distance is the same as the one determined above.

When we substitute the numbers, we obtain:

Speed = 13 hours / 650 km

50 km/hr speed

For the train to arrive at its location in 13 hours, it must move at a pace of 50 km/h.
