Answer:
DISTANCE
SPEED FORMULA = TIME
DISPLACEMENT
VELOCITY FORMULA = TIME
1.Displacement: 900 meters West
Time: 50 seconds
So, 900 ÷ 50 = 18 m/s west
2.Displacement: 24 meters
Time: 3 second
So, 24 ÷ 3 = 8 m/s
3.Displacement: 120 km North
Time: 5 hours
So, 120 ÷ 5 = 24 km/hr North
4.Displacement: 90 km
Time: 4 hours
So, 90 ÷ 4 = 22.5 km/hr
5.Displacement: 90 miles Southeast
Time: 5 hours
So, 90 ÷ 5 = 18 mi/hr
