Answer: He drove 120 miles each way
Step-by-step explanation:
Speed = Distance/Time
Since the distance in both ways is same, we take it as x.
Case 1 : 60 = x/t - (1)
Case 2: 40 = x/(t+1) - (2)
From 1 and 2
60t = 40(t+1)
20t = 40
T = 2 Hrs
Putting the value in (1)
x = 60 X 2
= 120 Miles
You can check the answer by putting the values in (1) and (2)

Answer:
120
Step-by-step explanation:
d=s×t & here each side distance is same
60 × x = 40 ( x + 1)
60x - 40x = 40 => 20x = 40 => x = 2
he drive 60 ×x = 60×2 =120 miles each way .
