SPEED CALCULATION
.....................................................................................................♣♣♣
➡ GIVEN :

➡ DISTANCE = 450 m

➡ DISTANCE = 0.45 km

➡ TIME = 2 MINUTES

➡ TIME = 2 × 60 s

➡ TIME = 120 s

➡ TIME = 1 / 30 h
.....................................................................................................♣♣♣
➡ SPEED = DISTANCE / TIME

➡ SI UNIT OF SPEED : m / s

➡ SPEED = 450 m / 120 s

➡ SPEED = 3.75 m / s
.....................................................................................................♣♣♣
➡ SPEED IN Km / h = DISTANCE / TIME

➡ SPEED = 0.45 km / 1 / 30h

➡ SPEED = 0.015 km / h
