time taken for Muthu = 1300-0800
= 5h
distance between A & B = 60x5
= 300 km
let speed of Lee be v
at 11.30 am, 1130-0900 = 2.5h has passed
distance travelled by Lee = 2.5 x v
= 2.5v
at 11.30 am, 1130-0800 = 3.5h has passed
distance travelled by Muthu
= 3.5 x 60
= 210 km
so
210 + 2.5v - 300 = 35
v = 50 km/h
time taken for Lee to reach A
= 300/50
= 6 h
time for Lee to reach A is
0900 + 0600 = 1500h
= 3.00 p.m.
