20

Step-by-step explanation:

The base square itself is 4 x 4 which is 16, then there are 4 halfs which makes 2 more and the other 2 in that 2 triangles so 20

15 minutes more, as 60-45mins = 15 minutes.

Step-by-step explanation:

Distance = 30 miles

Speed = 30mph = 1 hr

Compared to Distance 30 miles

Speed = 40mph  = 3/4 of 60mins = 45 mins.

1hr = 60mins = 60-45 = 15 minutes.
