Answer :
In the first trip The car travels 70 km in 3 hours so in 1 hour it will travel =>
3 hrs..... 70 km
1 hr..... 70/3 km
Now
In the second trip The car travels 120 km in 2 hours so in 1 hour it will travel =>
2hrs..... 120 km
1 hr..... 120/2 = 60 km
Now,
Average distance travelled in 1 hour = (distance travelled by the car in first trip + distance travelled by the car in second trip)/2
Average distance = {70/3 + 60} / 2
= {(70 + 180)/3}/2
= (250/3)/2
= 250 / 3 × 2
= 125/3
= 41.6667 km in hours
