Answer:
61
Step-by-step explanation:
The Pythagorean Theorem is a fundamental in geometry that involves looking at two sides of a right triangle and finding out the length of it. Let's use the formula with the corresponding numbers.
The formula for this question would be 
Since we know that a = 11 and b = 60, we can do the following and substitute :

11 squared is 121
60 squared is 3600
Now we need to add the two number together :
121 + 3600
3721
Since this number is under the square root, we have to square root it. :

61
Therefore c is equal to 61.
Answer:
we know that, 1miles/hour = 0.45m/s
or, 1meters/second = 1/0.45
1m/s = 2.22222222222
Step-by-step explanation:
Then,
72.0 meters/second = 72.0*2.22222222222
=160 miles per hour.
