Question

ek bus 7hours ke liye yatra krti h phela bhaag 30km /h or dusra bhaag 40km/h tye krti h duri yaad kijiye

Answer 1

let total distance 2x
so first x in speed 30
so
30=x/3.5
x=105km
so total path 210km

Answer 2

let 1st half distance=x=2nd half distance
t1= x/30
t2=x/40
t=t1 +t2 = x/30+x/40 = 4x+3x /120=7x/120
7=7x / 120
1x=120
x=120km
total distance=2x=240 km
