Answer:

▶let the time from 8.00am to the catch-up time be t hrs.

distance covered by Lewis = 10t

distance covered by John = 8t+{ 1/2 } { 60 }

= 8t+30

2t=30

t = 15

15 min added to 8:00am would make it 8:15 am

Lewis went 10t = 10 { 15 }

t= 150 min

John went = 8t + 30

= 8 { 15 } + 30

= 120 + 30

= 150 min

Hope it's Help You :)
