Question

A driver of an auto rickshaw sees a lorry 60 meters ahead of him.After 30 seconds the lorry is 90 meters behind.If the speed of the auto rickshaw is 38km/h,then what is the speed of the lorry?​

Answer 1

Answer:

5.55 m/s

Step-by-step explanation:

V(relative) = (90+60)/30 = 5 m/s

V(auto) = 38×(5/18) = 10.55 m/s

Therefore, V(lorry) = 10.55-5 m/s = 5.55 m/s

Answer 2

Answer:

the speed of the lorry is 9.5km/ hr.
