Answer:
41.05 mile per hour
Step-by-step explanation:
let distance of one leg be x
1st leg time: x/30
2nd leg time: x/65
total travel time = x/30 + x/65
total distance traveled = x + x = 2x
average speed = distance / time
= 2x / (x/30 + x/65)
= 2 / (1/30 + 1/65)
= 41.05 mile per hour
41.05
30*65*2/(65+30)
