What is the distance between A and B? Round your answer to the nearest tenth. (4 points) A: 6.4
B: 7.3
C: 8.2
D: 9.1

Step-by-step explanation:

the distance between two points can be considered the Hypotenuse (baseline) of a right-angled triangle created by the x and y coordinate differences of the points.

and then we simply use Pythagoras :

c² = a² + b²

with c being the Hypotenuse, and a and b being the legs of the coordinate differences.

A = (-1, 5)

B = (4, 1)

AB² = (-1 - 4)² + (5 - 1)² = (-5)² + 4² = 25 + 16 = 41

AB = sqrt(41)

41 is larger than 36 (= 6²), so its square root is therefore also larger than 6.

41 is smaller than 49 (= 7²), so its square root is therefore also smaller than 7.

the only answer option been 6 and 7 is A : 6.4

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
