Answer:
150 mph

Step-by-step explanation:
Let the rate of the plane be x. Distance traveled by plane=540 miles. Time taken by plane=540/x. Distance traveled by car=180 miles. Rate of car=x-180.Time taken by car=180 / x-120.The time taken by both are same
540/x=180/x-120
540(x-120)=180
540x-54000=180x
540x-180x=54000
360x=54000
x=54000/360
x=150 mph
