Ok to start you need to break this into a net in your head. Next, calculate each triangle
(6*7)/2 = 21
Then, multiply each triangle by the amount of them.
21*4 = 84
Next, get the area of the square.
7*7 = 49
Lastly, add the triangles and the square up.
49 + 84 = 133

Sergeeva-Olga [200]

Answer:

The correct answer is 54 miles per hour

Step-by-step explanation:

To solve this problem we have to use the formula of

Speed=Distance/time

Both, car an truck made the same distance,  so

Distance car=Speed car*time car

Distance truck =Speed truck*time truck  

Distance car=Distance truck

So Speed car*time car =Speed truck*time truck  

Speed car =Speed truck* time truck /time car

Time truck = time car +2 ( truck leaves 2 hours before)

Time car =10

Speed car =45 miles per hour* 12 /10

Speed car = 54 miles per hour
