Speed is the rate of distance over time.
<em>The speed of the boat is 13mph south-west</em>
Given
<em />
<em> --- west</em>
<em />
<em> -- south</em>
<em />
The speed is illustrated with the attached image
Because both speeds act at a diagonal, the speed (v) of the boat is calculated using Pythagoras theorem as follows:
Take square root
<em />
<em>Hence, the speed of the boat is 13mph south-west</em>

Answer:
2 hours
Step-by-step explanation:
Downers grove = 5 inches of snow + 6 inches every hour
= 5 + 6h
Woodridge = 13 inches + 2 inches every hour
= 13 + 2h
Where,
h = number of hours
In how many hours will the snowfall of the towns be equal?
Equate the snow falls of the towns
Downers grove = Woodridge
5 + 6h = 13 + 2h
Collect like terms
5 - 13 = 2h - 6h
8 = 4h
Divide both sides by 4
h = 8 / 4
= 2
h = 2 hours
The snowfall of the towns will be equal in 2 hours
Answer:
a=3
Step-by-step explanation:
This should be very simple, just substitute xy and y for 5 and 7 respectively, so 5a-2*7=1, or 5a-14=1, or 5a=15, if we divide both sides by 5, we get a=3
