A cargo plane flew to Moscow and back. It took 2 hours less time to get there than it did to get back. the average speed on the trip there was 245 km/hr. The average speed on the way back was 230 km/hr. How many hours did the trip there take?
***
let x=travel time of trip to Moscow
x+2=travel time on the way back
distance=travel time*average speed
245x=230(x+2)
245x=230x+460
15x=460
x≈30.7
How many hours did the trip there take? 30.7 hrs
