A km/hr = [a×5÷18]m/s.
60 = [9×5÷18].
5÷2×60 = 150 meter.
60 = [9×5÷18].
5÷2×60 = 150 meter.

= 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.

First we converted into m/s to speed.
So length = speed *time.
So, length =50 * 3 = 150.
So length = speed *time.
So, length =50 * 3 = 150.
