A vehicle moving at a constant speed travels 45 miles in 3/4 hour. How far will the vehicle travel in 2.5 hours? Use the formula d = rt, where d = distance, r = rate, and t = time, to solve. The vehicle will travel miles.

150 miles

Step-by-step explanation:

45              x

---        =     ---

.75              2.5

solve for x using a proportion (2.5)(45)/(.75)

x=150

a. is correct

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
