Answer:
44 mph
Step-by-step explanation:
Given that:
Before lunch :
Time taken = 2hrs ; at speed = x mph
After lunch :
Time taken = 3hrs ; at speed = x + 10 mph
Total distance covered = 250 miles :
Distance = speed * time
(2 * x) + (3 * (x + 10)) = 250
2x + 3x + 30 = 250
5x + 30 = 250
5x = 250 - 30
5x = 220
x = 220/ 5
x = 44 mph
Rate before lunch is 44mph
I need to know the distance.
speed= distance/ time
If you want to figure thier speed you need to divide the distance ( miles) by their time ( hours)

-5x/-5 = 1/-5
Simplify
Cancel terms that are in both the numerator and denominator
-5x/-5=1/-5 x=1/-5
Divide the numbers
x=-1/5
Step-by-step explanation:
ANSWER x=-1/5
Area of sector CAD = 72 / 360 x pi x 6^2 = 7.2pi = 22.6195 in^2
Therefore, area of segment CED = 22.6195 - 17.18 = 5.44 in^2
