And
what is the drivers distance as he drops his child off at school and then goes to the gas station?

20 mi, w

30 mi, w

30 mi

60 mi

The total distance covered by the driver is 60 mile.

Explanation:

Distance from house to school : AB = 25 mile - 10 mile = 15 mile

Distance from school to gas station =  BC

BC = 25 mile + 20 mile = 45 mile

Total distance covered by the person :

AB + BC = 15 mile  + 45 mile = 60 mile

The total distance covered by the driver is 60 mile.
