a motor bike travels 240 km in 4 hours. How long will it take to travel 450 km​

Answers

Answer 1

Answer:

7 hours and 30 minutes

Step-by-step explanation:

[tex]240 \div 4 = 60km \: per \: h[/tex]

[tex]450 \div 60 = 7.5 = 7h \: 30min[/tex]

Answer 2

It will take motor bike 7.5 hours to cover 450 Km of distance.

What is Speed in Kinematics?

Speed of a body is defined as the distance travelled by it per unit time taken to cover the distance.

Mathematically-

S = Δd/Δt  or   S = {d(2) - d(1)}/{t(2) - t(1)}

It is a scalar quantity as it only has magnitude and no direction.

Given is a motor bike travels 240 km ins 4 hours.

We can calculate the speed of the bike as -

s = 240/4 = 60 Km/hr

Then, the time taken to cover 450 Km will be -

t = 450/60

t = 7.5 hours

Therefore, it will take motor bike 7.5 hours to cover 450 Km of distance.

The trainers at Atlantis Aquarium perform shows about sea life. Yesterday, they performed 4 shows in 2 hours. Today, they will perform 6 shows. If they perform shows at the same rate, how many hours will the trainers spend performing shows today?

Answers

Answer:

3 hours

Step-by-step explanation:

Number of shows : Time taken

= 4 : 2

Today, they will perform 6 shows.

Number of shows : Time taken

= 6 : x

Equate both ratios to find x

4 : 2 = 6 : x

4/2 = 6/x

Cross product

4 * x = 2 * 6

4x = 12

x = 12/4

x = 3 hours

The trainers will spend 3 hours performing shows today

A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?

Answers

Answer:

31.25 kg of flour is needed to make 50 cakes

Step-by-step explanation:

A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?

We can find it by using unitary method i.e first find quantity of flour needed for 1 cake and then we can find quantity of flour needed for 50 cakes.

Flour needed to make 4 cakes = 2.5 kg

Flour needed to make 1 cake = [tex]\frac{2.5}{4}[/tex] kg

Flour needed to make 50 cakes = [tex]\frac{2.5}{4}\times 50[/tex]

                                                      = 31.25 kg

So, 31.25 kg of flour is needed to make 50 cakes

How many points does the team have?

How many games has this team lost?

Answers

Step-by-step explanation:

P = 3W + D

When W = 5 and D = 3, P = 3(5) + 3 = 18.

When P = 50 and D = 14,

(50) = 3W + (14), 3W = 36, W = 12.

Since the team has 12 wins and 14 draws,

they have 35 - 12 - 14 = 9 losses.

How many solutions are there to the equation shown below? 7x+12=5x−8

Answers

Answer:

Only one and that one solution is -10

Step-by-step explanation:

Answer:

One Solutionx = -10

Explanation:

7x + 12 = 5x − 8

Subtract 12 from both sides

7x + 12 - 12 = 5x - 8 + 12

Simplify

7x = 5x - 20

Subtract 5x from both sides

7x - 5x = 5x - 20 - 5x

Simplify

2x = -20

Divide both sides by 2

2x / 2 = -20 / 2
