Velocity is similar to speed in that it describes how fast an object is moving. However, velocity also specifies the direction the object is moving and is often expressed in meters per second. Suppose it takes a bicyclist traveling east on a bike path about 3.5 seconds to travel approximately 100.0 meters. What is the velocity of the bicycle? Express your answer using the appropriate level of accuracy and use complete sentences to explain your reasoning.

28.5714m/s East.

Step-by-step explanation:

-Velocity is defined as directional speed and is calculated as the quotient of displacement over time.

-Given the displacement as 100.0m and the time for that displacement as 3.5seconds and the direction as east, the velocity is calculated as;

Hence, the cyclist's velocity is 28.5714m/s East.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
