Solution 1

Using the conversion,

1 km/h = `5/18` m/s

18 km/h = `18xx5/18` = 5 m/s

Therefore, distance can be obtained using the relation:

Distance = Speed × Time = 5 × 1 = 5 m

Hence, the vehicle covers 5 m in 1 s

Solution 2

Speed of vehicle = 18 km/h = 18 x 1000/3600 m/s

= 5 m/s  so the vehicle covers 5 m in 1 s. = 11.3
