Correct question : A train starts at 1:30 P.M. from platformA at a speed of 72 km/hr then what time

will it reach the station 126 km away

Given :

A train starts at 1:30 P.M. from platformA at a speed of 72 km/hr

To find :

The time when the train will reach the station

Solution :

Step 1 of 2 :

Write down the speed of the train and distance to be covered

Here it is given that the train starts at 1:30 P.M. from platformA at a speed of 72 km/hr

The train need to reach the station 126 km away

Speed of the train = 72 km/hr

Distance to be covered = 126 km

Step 2 of 2 :

Calculate the time taken to reach the station

The time taken to reach the station

$\displaystyle \sf{ = \frac{126}{72} \: \: hour }$

$\displaystyle \sf{ = \frac{7}{4} \: \: hour }$

$\displaystyle \sf{ = \frac{7}{4} \times 60\: \: minutes }$

$\displaystyle \sf{ = 105\: \: minutes }$

$\displaystyle \sf{ = 1 \: hour\: 45 \: minutes }$

Step 3 of 3 :

Find the time when the train will reach the station

The train starts at 1:30 P.M. from platformA

Hence the time when the train will reach the station

= 1 : 30 PM + 1 hour 45 minutes

= 3 : 15 PM
