Answer:
C. 55s
Step-by-step explanation:
I'll refer to Wyndham as W and Michael as M.
Also, we will be assuming constant speed for both runners.
So, first of all, W ran with a speed of 8m/s;
400m/50s = 8 m/s
M ran with speed 9.2635.... m/s;
400m/43.18s = 9.26.... m/s
The difference is 1.26.... m/s, meaning every second, the distance between M and W would increase by 1.26.....m, starting from 0 at the start line;
9.26... - 8 = 1.26....
So, to find the desired distance, we simply multiply 1.26... by 43.18;
1.26... × 43.18 = 54.560....
(Rounded up to 55s)
196.9 miles
231.3 miles - 34.4 miles = 196.9 miles
Answer:
33 feet.
Step-by-step explanation:
If the ratio of the student to their shadow and flagpole to its shadow are equal, then you can use the proportion
5.5/3 = x/18 and cross multiply to find x.
5.5 × 18 = 99
3 × x = 3x
3x/3 = x, 99/3 = 33.
x = 33.
