Answer:

Step-by-step explanation:
<u>Constant Speed Motion
</u>
When the object travels the same distances in the same period of time, the speed is constant and is can be calculated as

where x is the distance and t is the time
There are two canoes traveling at speeds v1 and v2. One of them has twice the speed as the other. Let's say

When t hours have passed, the canoes have traveled x1 and x2 respectively.


Since

Then

The distance between them is


That distance is known and equals 11.25 miles, thus

Solving for v1 and using t=4.5 hours




Hello! i can do the first word problem
first we need to divide 600/3 which is 200.
therefore we can infer that he does 200 letters an hour and we can solve the problem with this
200 x 7 = 1400 letters an hour
Answer:
17 is your answer
Step-by-step explanation:
Wrong,
You added when you were supposed to divide.
24/30 = 0.8
Step-by-step explanation:
10×10+24×24= third side ×third side
third side ×third side =100+576
third side × third side=676
third side=√676
third side=26
