distance=750 m
speed = 10km/hr
= 10*1000 m/3600sec
distance/speed= time
750*3600/10000= time
75*36/10= time
15*18= time
270sec= time
time = 4min 30sec
this is the ans

run 10 km in 1 hour=60m
run 1km=1000meter in 60/10m=6m
run 1 meter in 6/1000
run 750 meter in 6×750/1000m=4.5m
so he run 750 meter in 4mintute 30seconds
ur ans is wrong it would be 4minute 30seconds.becouse if he runs 10km in 1km.how he need 4hours 30mins to run 750 meter.
