Question
A vehicle moving with a speed of 18 km h–1covers....m in 1 s
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
Is there an error in this question or solution?
