The ratio of 256km in 4h is speed.
Speed = 256km/4h = 64km/h
64:256 = 1:4
1 to 4
0.00063
1 over 4.
512:256:128 = 4:2:1
280 kilometers / 4 hours = 280/4 kilometers per hour = 70 kilometers per hour
It is 15:4.
As speed is ratio of distance and time...therefore upon calculating, you will get speed of 4 Km per hour.
If Danny travels 99 Kilometers in one hour then travelling at the same speed he will travel 99 x 4 kilometers in 4 hours, which is 396 kilometers.
There are 24 hours in one day, therefore 4 days is equal to 24 x 4 = 96 hours. The ratio therefore is equal to 57:96, which, in its simplest form, dividing both sides of the ratio by 3, is equal to 19:32.
194 hours/4 days = 194 hours/96 hours = 194/96 = 97/48
1.5 is the ratio. in other words it is 150% or one and a half times.
