Question

21. The distance between two towns T1 and
T2 is 400 km. Two cars A and B start
simultaneously from T1 and T2 towards
each other. The speed of A is 60 km h'
and that of B is 40 km h-'. The point
where two cars will meet is at
(a) 240 km from T1
(b) 200 km from T1
(c) 300 km from T2
(d) 170 km from T2​

Answer 1

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
