Multiplying and Dividing Exponents are very easy.
When they are multiplied, we add the exponent numbers together.
When they are divided, we subtract the exponent numbers.
In this example, h^{-18}* h^3/h^{0}
We can conclude that h^{0} is 1 because,
any number to the power of 0 is 1
\frac{ h^{-18}*  h^{3} }{1}=h^{-18} *  h^{3}
take the exponents alone:
-18+3 (Because it is multiplication) =-15
Final answer: h^{-15}

Maury completed a bicycle race 1.5 hours faster than Vince at an average speed of 16 miles per hour. Vince completed the same ra
MAXImum [283]
Let the time taken by Vince to complete the race was x hours. 
Maury completed the race 1.5 hours faster. This means Maury complete the race in (x - 1.5) hours.

Average Speed of Maury = 16 miles per hour
Average Speed of Vince = 12 miles per hour

Distance = Speed x Time.

For Maury:
Distance = 16(x - 1.5)

For Vince:
Distance = 12x

Since the distance covered by both was the same, we can equate the two equations as:

16(x - 1.5) = 12x
16x - 24 = 12x
4x = 24
x = 6 
This means Vince complete the race in 6 hours.

Distance = Speed x Time = 12 x 6 = 72 miles

Thus, the total distance of the race was 72 miles.
