Answer:
a. 240km from T1
Explanation:
total distance =400km
relative velocity (speed) = 60+40=100km/h
(add because moving toward each other)
time taken to meet at a point, T=distance / speed
=400/100
=4hr
so they meet after 4 hr
so they meet at 240 or (60×4) km from carT1
and 160 or (40×40) km from car T2
