Answer:

50 m/s

250 m

Step-by-step explanation:

180 km/hr × (1000 m / km) × (1 hr / 3600 s) = 50 m/s

50 m/s × 5 s = 250 m

A pilot can travel for 140 miles with the wind in the same amount of time as 360 miles against the wind. Find the speed of the w

quester [9]

Answer:

-88 mph

Step-by-step explanation:

We can use the relation ...

time = distance/speed

to compare the times in the two directions.

$\dfrac{140}{200+w}=\dfrac{360}{200-w}\\\\140(200-w)=360(200+w)\\\\200(140-360)=w(360+140)\\\\w=\dfrac{200(-220)}{500}=-88 \quad\text{miles per hour}$

The wind speed is -88 miles per hour.

_____

The problem statement tells us the travel is slower <em>with</em> the wind than <em>against</em> the wind. Hence "with the wind" must be subtracting from the net speed. That is, the wind speed is negative.

Please help!! Explain how you got the answer!

mash [69]

multiply 3.5 x 3 = 10.5

add -5 +-10 = -15

so you have 10.5 x 10^15

then you need to move the decimal point 1 place to the left to get 1.05

since you move the decimal point 1 place to the left you add 1 to the -15 to get -14

so answer = 1.05 x 10^-14
