Question

exppress ratio i n simplest form- 15m/s to 108km/h

Answer 1

15m/1second
and108km/h=108×100/60×60
10800m/3600s=3m/s
15m/s to 3m/s
or 5:1

Answer 2

The simplest form of the ratio is 1:2

• First numerical term of the ratio

= 15m/s

• Second numerical term of the ratio

= 108km/h

[Now,we have to convert this value into m/s unit form, because ratio of two similar kind of units is only possible]

= (108×1000)m / (60×60)s [ Conversion terms : 1 km = 1000 m ; 1 hour = 60 minute = 3600 seconds]

= 108000m/3600s

= 30m/s

• Now,we have to calculate the final ratio,

= 15 m/s : 30 m/s

= 15:30 ( similar units are always eliminated in the ratio to get the number only final ratio value)

= 1:2

The necessary ratio is 1:2 (answer).
