Angle D is 60° because it is a supplementary angle, meaning 180 (straight line) - 120 (angle A) = 60°
Answer:
43 minutes
Step-by-step explanation:
- <em>Let cycling speed be x and driving speed be y</em>
<u>Equations as per given, considering same distance in both cases:</u>
- 19x + 8y = 13x + 10y
- 19x - 13x = 10y - 8y
- 6x = 2y
- 3x = y
We see that driving speed is 3 times greater than cycling speed
Then 8 minutes driving = 8*3= 24 minutes of cycling, or 10 minutes of driving = 10*3= 30 minutes of cycling:
- 19 + 24 = 43 minutes or
- 13 + 10*3 = 43 minutes is the time to cycle between A and B
The factors is 5,4,3,6,12
The answer should be 7/8. simply just enlarge all of the fractions
their LCM is 40,
there fore, the question is 30/40, and the choices will be 20/40, 16/40, 25/40 and 35/40, there fore only 35/40 is larger than 30/40, so the answer is 7/8
