- Total timeof Ndiba =1+3=4hours

Let
- Ndibas speed be x
- Willies speed=x+10
Both travelled same distance



Answer:
25 degrees
Step-by-step explanation:
In the picture attached, the lines and the angles are shown. There we can see that:
85° + 2x° + (x-10)° = 180°
75 + 3x = 180
x = (180 - 75)/3
x = 35°
∠3 and ∠(x-10)° are alternate interior angles, therefore they are congruent, so:
∠3 = x - 10
∠3 = 35 - 10
∠3 = 25°
3x -x + 8 + 5x - 2 = 10
3x - x + 5x = 10 -8 +2
7x = 4
x = 7/4
Answer: 54
Step-by-step explanation: Step 1 i checked how many each one has and multiplied it by all of the numbers there were there by using a plus the hours are 54
