To calculate the speed at which an object travels, you can use the formula: speed = distance/time. In this case, the speed would be 90 km/3 hours = 30 km/h. This means that the object is traveling at a speed of 30 kilometers per hour.

It's speed - which is 90 Km/h
An hour is a unit of time. A kilometre is a unit of distance. Without some comparitive unit of speed, the two units are incompatible.
about 150 km 1.5 hours x 100 km = 150 km
Time = Distance/Speed = 450/90 = 5 hours.
To work this out multiply 90 by 2.5. Like this 90 x 2.5 = 225Therefore a motorcycle will travel 225 kilometers in 2.5 hours at 90 kph.
90 kilometres per hour.
30 km
To calculate the speed at which an object travels, you can use the formula: speed = distance/time. In this case, the speed would be 90 km/3 hours = 30 km/h. This means that the object is traveling at a speed of 30 kilometers per hour.

Speed = distance/time km/hr = 90km/3hr 90/3=30 30km/hr
TIME = DISTANCE divided by SPEED TIME (hours) = DISTANCE (km) divided by SPEED (km/h) TIME = 9KM divided by 6KM/H TIME = 1.5 Hours or 90 minutes
90km divided by 3 hours is 30km per hour
It's speed - which is 90 Km/h
At 30 kilometers per hour, in each hour you will cover 30 km. So after 3 hours you will have covered 3*30 = 90 kilometers.
3 hrs & 34 minutes is the same as 3.56666666666 hours. Divide this into 90 km and your answer is 25.233645 km/h (average)
