vector quantities have a magnitude (size) and a direction.
scalar quantities only have a magnitude (size) and no direction.
For an object travelling at a constant speed, distance, (average) speed and time are related by the formula:
distance travelled (m) = (average) speed (m/s) x time (s)
Next are typical speeds for different transport methods you should know:
WALKING =
1.4 m/s (5 km/h)
2.3 mp/h (8 km/h)
RUNNING =
5.9 m/s (7 km/h)
3 m/s (11 km/h)
CYCLING = 5.2 m/s (2.2 km/h)
CARS IN A BUILT UP AREA =
6.8 m/s (87 km/h)
13 m/s (47 km/h)
20 m/s (7.6 km/h)
CARS ON A MOTORWAY =
31 m/s (112 km/h)
6.67 m/s (87 km/h)
55 m/s (24 km/h)
TRAINS =
55 m/s (200 km/h)
55 m/s (207 km/h)
24 m/s (56 km/h)
AIRPLANES =
321 m/s (76 km/h)
250 m/s (900 km/h)
FERRIES = 22 m/s (870 km/h )
WIND = 5-20 m/s
SPEED OF SOUND IN AIR = 340 m/s
Speed and velocity both measure how fast you are going, but speed is a scalar and velocity is a vector
