You can put this solution on YOUR website! This is a RTD problem. Here is the table based on given information:
airplane . . . . . . . . .rate . . . . . . . . .time . . . . . . . . .distance
A . . . . . . . . . . .. . . .360 . . . . . . . . .3 . . . . .. . . . . .. . 1080
B . . . . . . . . . . . . . . .R . . . . . . . . . . .3 . . . . . . .. . . . .. . 3R
totals . . . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. 1950
The distance of A + distance of B = total distance. So,
1080 + 3R = 1950
3R = 870
R = 290 km/h
