The conversion between m and km are given .On finding the relation we get as follows . we know that , 1 km =1000 mm the ratio is between 400 m :1 km. now,400 : 1000. =2 :5.
There are about 8 km in 5 miles
400 m is equal to 2/5 of 1 km.
Since 1 km = 1,000 m, 2,000 = 2 km. So you have 5 km to 2 km (the same unit). Now you can write 5 km as the numerator since it is on the left of to, and 2 km as the denominator since it is on the right of to. Such as, 5 km/2 km (simplify) = 5/2
Average speed = Distance/Time = 400 km /5 hours = 80 km per hour.

To calculate the time it would take to travel 400 km at a speed of 80 km per hour, you would divide the total distance by the speed. So, 400 km divided by 80 km per hour equals 5 hours. Therefore, it would take 5 hours to travel 400 km at a speed of 80 km per hour.
250 and 400
There are about 8 km in 5 miles
It is: 400/5000 = 2/25 in its lowest terms
It is not. Suppose I cycle at 20 km per hour and a car travels at 50 km per hour. So the ratio of the speeds is 20/50 or 2/5. In 4 hours I will travel 80 km while in half an hour the car will travel 25 km. The ratio of the distances is, therefore, 80/25 = 16/5 which is NOT 2/5.
400 m is equal to 2/5 of 1 km.
You either reduce the numbers an keep the units or, if possible, you convert the units to the same. For example, the ratio 50 km : 30 minutes can be reduced to 5 km : 3 minutes or even 1.66... km : 1 minute. 50 km : 10 metres can be reduced to 5 km : 1 metre but, since 5 km = 5000 metres, the reduced ratio is 5000 metres : 1 metre which is 5000 : 1.
Since 1 km = 1,000 m, 2,000 = 2 km. So you have 5 km to 2 km (the same unit). Now you can write 5 km as the numerator since it is on the left of to, and 2 km as the denominator since it is on the right of to. Such as, 5 km/2 km (simplify) = 5/2
Average speed = Distance/Time = 400 km /5 hours = 80 km per hour.
It is a rate. For instance, if the quantities are 10 km and 2 hours, then the ratio (10 km)/(2 hours) = 10/2 km/hour = 5 km/h, which is a rate of speed.
A numerator or a denominator can be a fraction itself, but you don't have to leave it that way. When dividing something by a fraction you multiply by the reciprocal of the fraction, so the ratio of A to B is equal to A x 1/B. The ratio of 1 mile per (8/5) km can be expressed as 1 mi / (8 km / 5), which equals 1 mi x (5 / 8 km). Performing the multiplication gives you the ratio of 5 mi / 8 km.
