Distance =s(s-150)*45/150*60
225=s(s-150)*45/150*60
225 * 200=s(s-150)
45000=s(s-150)
Option: b) 300
Yes
Epdi 200 Vanthuchu.. Plz Explain

For work out sum 30km/h and 40km/h
240km is the distance
s (s-150)
~~~~~~
45/60 min
Distance=225km
Distance=s×(s-150)/150 × 45/60
225=s×(s-150)/200
s×(s-150)=225×200=45000
Actual Speed=b)300 km/hr
1 workout
S1=30 S2=40 Total time=14
D=s1×s2/s1+s2 ×total time
=30×40/70×144
=240km/hr
D=(S1*S2/S1+S2)*Total time=(30*40/30+40)*14
(1200/70)*14=240km
ANS : 240Km

so... 4:3=7
7 part === 14
4part====8
3part====6
ans 30×8==240
or
ans 40×6==240
D=S1*S2/S1+S2 *T
D=30*40/70*14=240KM
D/30+D/40 = 14
7D/120=14
D=240
