= 60×5/18.
= 300/18 (50×6=300 ,3×6=18).
= 50/3,
= 50/3×9,
= 50×3,
= 150.
= 300/18 (50×6=300 ,3×6=18).
= 50/3,
= 50/3×9,
= 50×3,
= 150.

Speed = 60 km/hr = 16.67 m/s.
Distance = Speed × Time = 16.67 × 9 = 150 m.
Distance = Speed × Time = 16.67 × 9 = 150 m.

60000 = 3600.
x = 9.
Cross multiply.
= 3600 x/60000*9.
Answer is 150.
x = 9.
Cross multiply.
= 3600 x/60000*9.
Answer is 150.

You can simply solve like this.
1 0mtrs/1hr * second.
1000/60 * 9 = 150.
1 0mtrs/1hr * second.
1000/60 * 9 = 150.

1 km = 1000 m,
1 hr has 3600 sec.
So, 1 km/hr = 1000m/3600s = 5/18 m/s.
1 hr has 3600 sec.
So, 1 km/hr = 1000m/3600s = 5/18 m/s.

1 km = 1000 m,

So, 1 km/hr = 1000m/3600s = 5/18 m/s.
1 hr has 3600 sec.
So, 1 km/hr = 1000m/3600s = 5/18 m/s.

Distance = Speed x time.
Length = (60 x 5/18) x 9.
= 150 MTRS.
Length = (60 x 5/18) x 9.
= 150 MTRS.
