The distance from point a and point is equal for travels going back and forth. They would just differ in time and speed because of the sea's speed that propels the vessel. The solutions as as follows:
Distance upstream = Distance downstream
99(t + 2) = (99 + 1)(t)
Solving for t,
t = 198 hours
That means that the distance is equal to:
Distance = 99 miles/hour * (198 + 2 hours)
Distance = 19,800 miles
A caldera is a large cauldron-like depression that forms following the evacuation of a magma chamber or reservoir. When large volumes of magma are erupted over a short time, structural support for the crust above the magma chamber is lost, and the entire structure caves in and forms a large bowl-like shape.
Answer:
43 m\s in the 10 seconds?
Explanation:
Answer:
a. slope=rise/run
rise=2
run=10
slope=2/10
slope=1/5
used point (0,0) and (10,2)
slope(m)=1/5
b. area= 0.5bh
0.5×50s×10m/s
a=25s×10m/s
a=250m
c.the area represents the total distance traveled after 50s by the toy
the slope represents the acceleration of the toy
the unit of slope is m/s²
slope=rise/run
slope(m)=(2m/s)÷10s
m=(2/10)m/s/s
m=(1/5)m/s²
.=0.2m/s²
