Aircrafts

Above the town hall tower flew the plane with constant speed 592 km/h and 15 minutes later the second plane at speed of 675 km/h. How long and how far from the town hall will be aircrafts caught up?

Result

t =  107 min
s =  1203.614 km

Solution:

592*(t+15) = 675*t
s = 675/60*t

83t = 8880
60s-675t = 0

s = 99900/83 ≈ 1203.614458
t = 8880/83 ≈ 106.987952
