Speed = 100/9 m/sec
time= 90 sec
distance= speed * time=1000m=1km (1)
speed=50/3 m/sec
time = 90 sec
distance = speed * time=0.5 km (2)
from (1) & (2)
total distance = 1.5 km
time= 90 sec
distance= speed * time=1000m=1km (1)
speed=50/3 m/sec
time = 90 sec
distance = speed * time=0.5 km (2)
from (1) & (2)
total distance = 1.5 km
