Question

Find Out the Distance Covered by the Train
A person covers 360 km in 6 hours. He covers some distance by bus at the average speed of 40 kmph and the remaining distance by train at the average speed of 70 kmph. Find the distance covered by the train?

Answer 1

let  the  person  travel  x  hours  by  bus.  so  he  travels  6 - x  hours  by

train.  so  the  equation  to  find  x  is

40 x + 70 ( 6 - x ) = 360     or   40 x - 70 x + 420 = 360  or

30 x = 60,  hence  x = 2. hence  distance covered by train = 70* 4= 280

Answer  280 km

Answer 2

Answer:

The distance traveled by train is 280 km

Step-by-step explanation:

We are given that A person covers 360 km in 6 hours.

Let x be the time taken to travel by bus

So, time taken to travel  by train = 6-x

Speed of bus = 40 kmph

Speed of train = 70kmph

Distance = $Speed \times Time$

We are given taht the total distance is of 360 km

So, Total distance = Distance traveled by bus + distance traveled by Train

So,$360 = 40x+70(6-x)$

$360 = 40x+420-70x$

$360 = 420-30x$

$60=30x$

x = 2

So, Distance traveled by train = 70(6-2) =70(4)=280 km

Hence The distance traveled by train is 280 km
