Answer:
Step-by-step explanation:
A)
Given Claire runs 10 km in 1 hour,
in half an hour, she runs half of 10km = 5km
In 2 1/2 hours, she run 2.5 times of 10km = 25km
B)
Given Malia runs 5 km in 1 hour,
in half an hour, she runs half of 10km = 2.5km
In 2 1/2 hours, she run 2.5 times of 5km = 12.5km
A) 5km, 25km B) 2.5km, 12.5km
A)Claire runs 10 km in 1 hour.
she runs 10/2=5km in 1/2 hour.
in 2 1/2, she runs 10*2 1/2=25km
B)Malia runs 5 miles in 1 hour.
she runs 5/2=2 1/2km in 1/2 hour.
in 2 1/2, she runs 5*2 1/2=12 1/2km
<em>It's </em><em>B</em><em>, the diagonals bisect each other</em>
If they were equal, it would have to be a rectangle. If they were perpendicular, it would have to be a sqaure.
3.74
Use Pythagorean theorem
2.5^2=x^2=4.5^2
x=3.74
