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.

Time = Distance/Speed = 400/80 = 5 hours.
250 and 400

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.
Well, darling, a 400 meter oval track means you have to run 2.5 laps to hit that 1 kilometer mark. So, to cover 5 kilometers, you'd need to strut your stuff for a grand total of 12.5 laps. So, lace up those shoes and get ready to make those laps your runway!
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.
