@Aditya.
15%+55% = 70,
30%?
12750÷ 30 = 425*70 = 29750 + 12750 = 42500ans.

@Jayath how about -14x/100. I do not understand. Where did you get the number?

Length = time/speed.
= 9sec/60kmhr.
= 0.15km = 150meter.
= 9sec/60kmhr.
= 0.15km = 150meter.

5/18 means 5 meters/18 seconds so 5/18 is the conversion of 1km/h.
Thank you.

Length = speed × time.
60*(5/18) = 50/3
(50/3)*9 = 150.
Length = 150 metres.
60*(5/18) = 50/3
(50/3)*9 = 150.
Length = 150 metres.

1 km = 1000 m.
60 km = 60000 m.
1 hr = 3600 sec.
= (60000/3600)*9 = 150m.
60 km = 60000 m.
1 hr = 3600 sec.
= (60000/3600)*9 = 150m.
