Question

A train is moving at the uniform speed of 75km/hr . 1- how far will it travel in 20 minutes ? 2- find the the time required to cover a distance of 325km/hr

Answer 1

The whole sum is in the S.I. Unit:

Speed= 75km/hr
         =  m/s
         =  m/s

1) Time= 20 mins= 20×60 secs= 1200secs
Distance = Speed×Time
D= ×1200 metres
D= 25000 m= 25 km

2) Distance= 250km = (250×1000) metre, Speed=
Time=
T=12000secs= 3.33 hours

Answer 2

Hi friend , Harish here.

Here is your answer:

Given:

Speed of train is 75 Km/hr

To find,

1)Distance traveled at 20 mins.

2)Time taken to cover 325 km.

Solution:

We know that,

$Speed= \frac{distance}{time}$

1) $Speed = 75\ km/hr$

    [tex]Time\ taken = 20min = \frac{20}{60}hrs = \frac{1}{3} hrs. [/tex]

    [tex]Distance= Speed\times time = 75 \times \frac{1}{3}= 25 Km. [/tex]

2) $Distance\ covered =325 \ km$

    $Time = \frac{Distance}{speed} = \frac{325}{75}= 4 \frac{1}{3}hrs = 4hours\ 20mins$
