Awoman walks due west on the deck of a ship at 4 mi/h. the ship is moving north at a speed of 16 mi/h. find the speed and direction of the woman relative to the surface of the water. (round your answers to one decimal place.) speed mi/h direction n °w

Speed of the woman walking = 4 miles/hours

Speed of the Ship travelling = 16 miles/hour

Speed of the woman relative to the surface water =

Speed of the woman relative to the surface of water =

Speed of the woman relative to the surface of water =

Speed of the woman relative to the surface of water =

Speed of the woman relative to the surface of water  = 16.5 miles per hours (Rounded to one decimal)

Her direction is given by tan Θ = 16/4 = 4

Θ = tan inverse of 4 = 75.96

Θ = 76 degrees north west

0.6

39mph

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
