Dear Student,
◆ Answer -
Speed of train = 50 km/hr
Speed of car = 75 km/hr
● Explaination -
Let v be speed of the train, then speed of car is v+25.
For the train,
t1 = 300/v
For the car,
t2 = 300/(v+100)
Total time taken is -
t1 + t2 = 10
300/v + 300/(v+25) = 10
300(2v+25) / v(v+25) = 10
Solving this,
v = 50 km/hr
So speed of train is 50 km/hr and that of car 50+25 = 75 km/hr.
Thanks dear for asking..
