Suppose they meet x hrs after 8 a.m.
then
(Distance moved by first in x hrs) + [Distance moved by second in (x-1) hrs]
= 300
So, 60x+75(x-1) = 300
x= 375/135 = 25/9 hours
x = 2hr 47 min approx
So,they meet at 10.47 am
then
(Distance moved by first in x hrs) + [Distance moved by second in (x-1) hrs]
= 300
So, 60x+75(x-1) = 300
