Question

Relation in between speed time distance is if d=135m t=10sec then find speed

Answer 1

D = 135 m
T = 10 sec
We know that,
Distance (D) = Speed (S) x Time (T)
Speed (S) = D/T
                 = 135/10 = 27/2 m/s or 13.5 m/s
Hence speed = 13.5 m/s or 48.6 km/hr
[13.5 m/s = 13.5 * 18/5 km/hr = 48.6 km/hr]
Hope it helps.
