Abdul travelled 300 kilometre by train and 200 kilometre by taxi it took in 5 hours 30 minutes but if he travels
Answers
Answer:
100 km/hr and 80 km/hr
Step-by-step explanation:
1st case :
distance travelled by train = 300km
and by taxi = 200km
Let speed of train be x km/hr and that of taxi be y km/hr.
so, time taken by train = d/s time taken by taxi = d/s
= 300/x = 200/y
total time taken = 5hrs 30 mins = 5 1/2 hrs
so, 300/x +200/y = 5 1/2 by solving we get : 600y + 400x = 11xy..........1
2nd case :
distance travelled by train = 260 km and by taxi = 240 km
here also speed of train be x km/hr and of taxi be y km/hr
Then time = d/s
train time= 260/x hr of taxi = 240/y hr
combiningly,total time =
260/x + 240/y = 5hrs 36 mins
=> or 260/x + 240/y = 5 3/5 on solving we get,
1300y + 1200x = 28xy...............2
eq 1 × 3 = 1800y + 1200x = 33xy
