- Total timeof Ndiba =1+3=4hours

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



Answer:
97
Step-by-step explanation:
The square of a number is the opposite of a root. If you have both on a number, they cancel out. The answer, therefore, is 97.
What I did was add all the x's since you are trying to find the perimeter then I got 16 and then you add the whole numbers. 16x+3
Maybe try using Photomath it works for me. Good luck
