40% decrease
If one's speed changes from 10 km/h to 6 km/h, one has decelerated.
distance (km) / speed (kph) = time (Hrs) if you go 1 km at 10 kph then: 1 / 10 = 0.1 but 0.1 hours isn't very helpful so: 0.1 X 60 = 6 it takes 6 minuets to go 1 kilometre at 10 kilometres per hour!

It is 3 x 10^6 km or 3 x 106 km
6 km in 45 minutes = 6/45 = 0.133 km per minute.
If one's speed changes from 10 km/h to 6 km/h, one has decelerated.
Yes, a decrease in speed from 10 km/h to 6 km/h represents a negative acceleration, also known as deceleration or retardation. This means that the velocity is decreasing over time.
average speed = total_distance/total_time = (80 km + 100 km)/(10 min + 20 min) = 180 km/30 min = 6 km/min 1 hr = 60 min → 6 km/min = 6 × 60 km/h = 360 km/h
6 km/h
You cover 100 km in one hour. 10 km is 1/10 of 100 km, so you need 1/10 of an hour = 6 minutes.
The total distance covered by the plane is 80km + 100km = 180km, and the total time taken is 10 minutes + 20 minutes = 30 minutes. Therefore, the average speed of the plane is 180km / 30 minutes = 6 km per minute.

Moving 12 km in 40 minutesMoving 6 km in 15 minutesMoving 10 km in 20 minutesMoving 18 km in 30 minutesThat’s the answer!
To calculate her average speed, you need to divide the total distance by the total time taken. In this case, the distance is 2.5 km and the time taken is 10 minutes (which is 1/6 hours). Therefore, the average speed is 2.5 km / (1/6) hours = 15 km/h.
It is 3 x 10^6 km or 3 x 106 km
We first set a proportion:60/10 = 25/xSolving yields:6 = 25/x6x = 25x = 25/6x = 4 1/6 km
