Answer:
The answer is 97% decrease
So first find time elapsed
10:40-11:40=1
11:40-12:40=1
12:40-1:10=0.5 or 30 mins
so add
1+1+0.5=2.5, 2 hours 30 mins
3 miles per hour
3 times numberof ohours
3 times 2.5
7.5
answer is 7.5 miles

How to find the rational numbers?</h3>
Remember that any integer is also a rational number.
So, if we want to find 5 rational numbers between -47 and 12, we can just find 5 integers between these two numbers.
To do that, we can just add 1 to the lowest bound, we will et:
-47 + 1 = -46
-45 + 1 = -45
-44 + 1 = -44
-43 + 1= -43
-43 + 1 = -42
So 5 rational number between -47 and 12 are {-46, -45, -44, -43, -42}

Answer:
b = 
Step-by-step explanation:
a^2 + b^2 = c^2 is the Pythagorean theorem
if A = 2 and C = 10 then you get
2^2 + b^2 = 10^2
or 4 + b^2 = 100
b^2 = 96
b = square root of 96 or approximately 9.8
