Frank is leaving Gainesville at 7:30 am and needs to be in Tampa by noon. He is cycling at an average speed of 18.3 mph. At what
garri49 [273]

If Frank leaves Gainesville at 7:30 am, the time he should arrive in Tampa is 12.00 pm after spending 4 hours 30 minutes on the road.

<h3>What is average speed? </h3>

The average speed of an object is the ratio of total distance to total time of motion.

V = total distance/total time

For Frank to be in Tampa by noon, he must spend atleast 4 hours 30 minutes on the road.

18.3 mph = d/4.5 h

d = 82.35 miles

The distance between Gainesville  and Tampa is 82.35 miles.

Thus, we can conclude that, if Frank leaves Gainesville at 7:30 am, the time he should arrive in Tampa is 12.00 pm after spending 4 hours 30 minutes on the road.

5. Find the mass of a car that is traveling at a velocity of 35 m/s West.
sattari [20]

Answer:

m = 9795.9 kg

Explanation:

v = 35 m/s

KE = 6,000,000 J

Plug those values into the following equation:

KE = \frac{1}{2} mv^{2}

6,000,000 J = (1/2)(35^2)m

---> m = 9795.9 kg

How does light interact with the fur of a black cat?
Rina8888 [55]

The answer is C

The colour that you see is what is being reflected and the colour that you don't see is what is being absorbed. In this case, you don't see any colour, so all wavelengths are being absorbed.

Foraging bees often move in straight lines away from and toward their hives. Suppose a bee starts at its hive and flies 500 m du
Ainat [17]

Answer:

The distance of the bee from the hive is 740 m.

Explanation:

Given that,

Bee starts fly 500 m due east, 430 m west and 670 m east.

The direction of the bee

500 m in positive direction

430 m in negative direction

670 m in positive direction

We need to calculate the net distance

Using formula of distance

D=500-430+670

D=740\ m

Hence, The distance of the bee from the hive is 740 m.
