Question

the distance between two cities is 380 km. A train takes 6 hours 40 minutes to cover the distance. Find the speed of the train


​

Answer 1

Answer:

60km/hr

Step-by-step explanation:

Speed= Distance/time

Time =6.4 hrs

and distance=380

3800/64=475/8

59.375

Approx 60 km/hr

Answer 2

. Distance between 2 cities = 380km

. train takes 6hour 40 minutes to travel this distance.

$\huge {\underline{\bf{\blue{TO\: FIND:}}}}$

. Speed of train

$\huge {\underline{\bf{\pink{Explanation:}}}}$

Note:- Times taken by train is given in both hours and minutes, So before finding our answer, we have to make time into only hours or in only minutes.

So, let's make time into only minutes :-

$we \: know \: that \: if \: we \: convert \: \: 1 \: hour \: in \: minute \: \: then \\ \: we \: find \: 60 \: minute$

Hence, we can say that,

1 hour = 60 minutes

so, 6 hours = 60×6 =360 minutes

nd time is already given 40 minutes, so we have to add 40 minutes in 3600 minutes,

=> 360+40 = 400 minutes.

so now , we have 380 km distance, and time taken by train to cover 380km is 400 minutes.

To find speed of train, we have to use formula of speed,

Formula of finding speed =

$s \: = \frac{d}{t} \\ where \: d \: = distance \: and \: t \: = time$

Finding answer by using this formula :-

speed of train = d/t

=> speed of train = 380/400

=> speed of train = 38/40

=> speed of train = 0.94km/m

So,

The speed of train = 0.94km/minutes.
