This is easy!
That's true! you can use the speed triangle to help you remember
you have to convert meters to centi-meters first;
800m = 80000 cm & 154m = 15400 cm
Now, Substitute that in your original equation;
80035 cm - 15449

Answer:
a. 0.0783
Step-by-step explanation:
We have these following probabilities:
A 15% probability that a flight is delayed
An 85% probability that a flight is on time
Which of the following is closest to the probability that it will take 5 selections to find one flight that is delayed?
We want the first four flights to be on time. Each flight has an 85% probability of being on time.We want the fifth flight to be late.
Each flight has a 15% probability of being late.
So
0.85*0.85*0.85*0.85*0.15 = 0.0783
So the correct answer is:
a. 0.0783
