Explanation:

Let both scooters meet after t hours from 10 a.m.
∴ Distance = Speed × Time
∴ Distance covered by scooter
A in t hours + distance covered by scooter B in (t - 2) hour = 140
= 50t + 30(t - 2) = 140
= 80t – 60 = 140 = 80t = 200
= t = 200/80 = 5/2 hours
i.e. after 2 hours 30 minutes i.e. at 12.30 p.m.
