The universal equation for discovering the speed of an object would be to divide the unit of measurement (in this case KPH) by time (5 hours). Or "Speed = Distance / Time"!
400/5 = 80 KMH
643.74/5 = 128.74 MPH

∙ 12y ago4km= 4000m
8min= 480secs
4000/480= 8.3333...etc
Therefore the speed of the object is :
8.3ms-1 (2sf)
or
8ms-1(1sf)

A cyclist travels at 16km per hour how far does he cycle in 15 minutes?
4km
What is the displacement for a driver who travels 10km to get a point that is 4km from his starting point?
The displacement is 4 km.
What is 4km turned into meters?
4km = 4,000m
What is a 4km in a meters?
4km is 4,000 meters.
How far can a person run in 15 minutes if he or she runs at an average speed of 16km per hour?
16*0.25 = 4km
A person can row downstream 20km in 2 hours and upstream 4km in 2 hours. find the speed of the current?
To do this, you need to form equations using the information given. There are 2 variables here, the base speed of the rower with no current (x), and the speed of the current (y). Firstly, convert the distances and times given into average speeds. 20km/2 hours = 10km/h 4km/2 hours = 2km/h The actual speed = the base speed +- the current, depending on direction. So 10 = x + y 2 = x - y If we subtract these 2 equations to eliminate x, we get: 8 = 2y y = 4km/h
A man lives 1 kilometre from a shop it takes him 15 minutes to walk to the shop what is his walking speed?
in what units? 1km/15min is a speed 4km/h (kilometers per hour) is the same speed 96km/day is the same speed
How long does it take to walk 2.1 km?
The average walking speed of humans is approximately 4km/h, so it would take about half an hour
Which is more 4km or 4002m?
4002m is the longer distance - it's 2 metres longer than 4km.
What is 95m plus 4km minus 225mm equals?
95m + 4km - 225mm = 4.094,775km, 4,094.775m, or 4,094,775mm
Is acceleration the change in distance over time?
acceleration is the change in speed in a certain amount of time eg a car goes from 4km/h to 10km/h in 3 seconds, what is its acceleration? 10km/h - 4km/h=6 6/3 secounds=2 acceleration is 2km/h acceleration= change in speed/time
A body travels from a-b with displacement 5km and from b-c with displacement 4km. The same body again travels from c-a through b .Find the displacement made by the body while moving from 1a-c 2journey?
displacement in second case is zero as the body returns to its initial point.
