A boy runs a distance of 16 km in 4/3 hrs find the speed in m/sec

2
Distance = 16km = 16000m            Time = 4/3hrs = 4800 sec      we know  Speed = distance*time = 16000* 4800 = 76800000m/sec 
my dear friend, speed is equal to distance upon time. s= d/t check ur science textbook
speed =distance/time  
oops sorry it is distance/time = 16000/4800 = 160/48 = 10/3 m/sec
sorry for the wrong one

Given,
   distance,d=16km=16X1000=16000m
   time,t=4/3hrs=4/3X60X60=4800sec
  
  speed=distance/time
 speed=16000/4800
  speed =10/3
 speed=3.33 m/sec
