Above the town hall tower flew the plane with constant speed 510 km/h and 15 minutes later the second plane at speed of 703 km/h. How long and how far from the town hall will be aircrafts caught up?

Correct answer:

t =  39.6 min
s =  464.4 km

Step-by-step explanation:

510 (t+15)/60=703 (t/60) s=703/60 t  193t=7650 60s703t=0  s=464.417098 t=765019339.637306=39.6 min
