Answer:
540 miles
Step-by-step explanation:
Let the number of times he travelled by automobile be T. If he travels a certain number of miles by automobile and then nine times as far by airplane, then the number of miles by airplane would be
= 9T
If his total trip was 600 miles in length then
T + 9T = 600
10T = 600
T = 60
By plane, he must have traveled
= 9 * 60 miles
= 540 miles
X +9x =600 10x=600 x=60 9x=540 miles, by plane.
