Answer 1

SOLUTION

GIVEN

A train covers a distance 3549 km to reach a station A in 42 h 15min.

TO DETERMINE

The speed of the train

EVALUATION

Here it is given that a train covers a distance 3549 km to reach a station A in 42 h 15 min.

Now total distance covered = 3549 km

Total time taken

= 42 h 15 min

$\displaystyle \sf{ = 42 + \frac{15}{60} \: \: hr }$

$\displaystyle \sf{ = 42 + \frac{1}{4} \: \: hr }$

$\displaystyle \sf{ = 42 +0.25 \: \: hr }$

$\displaystyle \sf{ = 42 .25 \: \: hr }$

Hence the required speed of the train

$\displaystyle \sf{ = \frac{3549}{42.25} \: \: kmph }$

$\displaystyle \sf{ = 84 \: \: kmph }$

FINAL ANSWER

The required speed of the train = 84 km/h
