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

I would say C because it makes more sense than all the others.
ok
1) -2.5, 0.11111...., 1/4, 5 4/5, sqrt51, sqrt 100
2) Using simplification,
-2.5 is smallest because its negative, and no other number is negative. 0.11111 is the second smallest
1/4 is 0.25, and the third smallest
5 4/5 is 5.8 and is the third biggest
sqrt of 51 is around 7.14, so its second largest
lastly, sqrt 100 is 10, making it the largest
3) 10-(-2.5)=12.5
