Answer:
Step-by-step explanation:
Let the speed of the car be "X". From 3 am until 1 pm (10 hours), the car will travel 10*X miles.
The speed of the airplane is (X +200). From 11 am until 1 pm (2 hours), the plane will travel 2*(X+200).
The distance travelled is the same, so:
10*X = 2*(x+200)= 2x+400
Subtract 2*X from both sides:
8*X = 400
X = 400/8 = 50 mph.
Answer:
1
Step-by-step explanation:
Start at -0.5 and go toward 0.5.
From -0.5 to zero, it's a distance of 0.5.
From zero to 0.5, it's also a distance of 0.5.
Add the two distances, 0.5 + 0.5 = 1.
The distance between -0.5 to 0.5 is 1.
