Steve can run 3.5 miles in 30 minutes. If Steve increases his rate by 1/2 mile per hour, how far will he run in 2 hours?
Sati [7]

Answer:

15 miles

Step-by-step explanation:

Steve runs 3.5 miles in 30 minutes (0.5 hours).  So his speed is:

r = 3.5 mi / 0.5 h

r = 7 mi/h

If his rate increases to 7.5 mi/h, the distance he runs in 2 hours is:

d = 7.5 mi/h × 2 h

d = 15 mi

Artaud noticed that if he took the opposite of his age and adds 40 he gets the number 28 how old is Artaud
grandymaker [24]
Artaud is 12 years old, because

28 = 40 + (-1)(x), x = Artaud's age
-1x +40 = 28
-x = -12
x = 12

You multiply x and -1, because that is how you get the opposite.
