Destination 7703

The glider took off from the airport at 10:00 a.m. and flew to the designated destination 102 km away at a speed of 80 km/h. Half an hour later, a motorplane took off behind him at a speed of 180 km/h. When does the motor plane catch up with the glider, and at what distance from the target?


t = 10:54 hh:mm Wrong answer
s =  30 km

Step-by-step explanation:

80 (x10.00)=180 (x10.5)  100x=1090  x=1001090=10.9  x=10109=10.9  t=x=10.9=10:54 hh:mm
s=10280 (x10.00)=10280 (10.910.00)=30 km
