Question

1. find the velocity of a turtle who swims 100 meters toward the shore in 20 seconds. v =? t = d = 2. find the velocity of a baseball thrown across a field, a distance of 40 meters. it takes the ball 4 seconds to cross the field. v =? t = d = 3. find the velocity of a car that travels north 80 km in 2 hours. *check your units! v =? t = d = 4. find the velocity of a dog that runs 120 meters towards a cat in 60 seconds. v =? t = d = 5. find the velocity of the cat that outruns the dog by doing the same 120 meters in 40 seconds. v =? t = d =

Explanation:

Step1: Recall velocity formula

The formula for velocity is $V=\frac{d}{t}$, where $V$ is velocity, $d$ is distance, and $t$ is time.

Step2: Solve for turtle's velocity

For the turtle, $d = 100$ meters and $t=50$ seconds. So $V=\frac{100}{50}=2$ m/s.

Step3: Solve for baseball's velocity

For the baseball, $d = 40$ meters and $t = 4$ seconds. So $V=\frac{40}{4}=10$ m/s.

Step4: Solve for car's velocity

For the car, $d = 80$ km and $t = 2$ hours. So $V=\frac{80}{2}=40$ km/h.

Step5: Solve for dog's velocity

For the dog, $d = 120$ meters and $t = 60$ seconds. So $V=\frac{120}{60}=2$ m/s.

Step6: Solve for cat's velocity

For the cat, $d = 120$ meters and $t = 40$ seconds. So $V=\frac{120}{40}=3$ m/s.

Answer:

1. $V = 2$ m/s, $t = 50$ s, $d = 100$ m
2. $V = 10$ m/s, $t = 4$ s, $d = 40$ m
3. $V = 40$ km/h, $t = 2$ h, $d = 80$ km
4. $V = 2$ m/s, $t = 60$ s, $d = 120$ m
5. $V = 3$ m/s, $t = 40$ s, $d = 120$ m
