The distance traveled can be calculated using the formula D
= S. t where s is the speed and t is the total time. Which of
the situations below represent a total distance of 120 km?
Select all that apply.
A) 40 km/hr for 3 hours
B) 60 km/hr for 2 hours
C) 30 km/hr for 4 hours
D) 25 km/hr for 5 hours

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

in my opinion , its hazel
