What is the average speed in kilometers per hour if you travel 194 kilometers in 4.1 hours?

1 answer:

8 0

47.317 or about 47.32kph is the average speed.

You could set this up as a standard ratio to help visualize how to solve this problem. For every 194 kilometers, 4.1 hours has passed in meaning the ratio would be 194:4.1. Next find what side would make 4.1 would change into 1 so you would do 4.1 divided by 4.1 which will give you 194:1. But with a ratio you need to divide on both sides of the ratio. So do 194/4.1 which would equal to about 47.317.

Steve travelled from Ashton to Barnfield.

USPshnik [31]

Answer:

67.1

Step-by-step explanation:

Given That:

Time = 200 minutes = 3.5 hours

Distance = 235 miles

We Know That:

Speed = Distance / Time

SO, Speed = 235 divided by 3.5 = 67.1428571

Round this 3sf = 67.1

Hope this helps.

Paolo paid $ 28 $ 28 for a hat that was originally priced at $ 35 $ 35 . By what percent was the hat discounted?

devlian [24]

The original price of the hat is $35. Paolo paid $28 for the hat.

So discount for the hat is $(35-28) = $7

$7 is discounted from $35. We have to find the percentage of the discount.

To find the percentage we have to divide the discount amount by the original price and then have to multiply it by 100.

So the discount percentage =

((7/35)×100) %

We can simplify 7/35 by dividing 7 and 35 both by 7. So we will get 1/5 after simplifying.

((1/5) ×100) %

(100/5)% = 20%

So the hat was discounted by 20%.

Question 1. It is graph 3 since the y-intercept in the equation is -2 and the y-intercept on the graph 3 is -2. It is also a quadratic function.

Question 2. It is graph two because the equation listed represents a quadratic function that is positive (graph opens up).

Question 3. It is graph 4 since the y-intercept is 2 and the only graph with that intercept is graph 4. Also, the equation represents a linear function.

Hope this helped :))
