Question

please answer this question

Answer 1

Speed = D/T
so 35/2 =17.5 km or 17500 m
5 hrs = 300 min and 18000 sec

distance/time = 175000÷300=58.333 or 58.34

so speed= 58.3333 m/min

d/t= 17500/18000= 0.972222

speed =0.9722m/sec

Answer 2

Speed = Distance/Time 
so 35/2 =17.5 km = 17500 m
5 hrs = 300 min =18000 sec

distance/time = 175000/300=58.34

so speed= 58.34 m/min 

d/t= 17500/18000= 0.97

speed =0.97m/sec
