Answer 1

Answer:

233.25 m

Step-by-step explanation:

SPEED OF BALA = 6 m/s

DISTANCE TO BE COVERED BY BALA = 400m

TIME TAKEN BY BALA = 400/6 sec = 66.67 sec

DISTANCE COVERED BY SAM IN THIS TIME =( 66.67 * 2.5)m =166.7m

So , the distance remaining to be covered by Sam = (400 - 166.67)m= 233.25m

Answer 2

Answer:

time in which Bala completed the race is 400/6 = 66.6 sec

time in which Sam completed race is 400/2.5= 160 sec

so in 66.6 sec he completed the distance is = 2.5×66.6= 166.5mtr
