Find the average speed of a horse that traveled east for 25 km in 4 hours

Answers

Average speed can be viewed as the rate of change in distance with respect to time. A car traveling at an average speed of 25 miles per hour covers an average distance of 25 miles every hour. So for a horse traveling 25 km in 4 hrs has an average speed of 6.25 km/ hr

The direction the horse travels has nothing to do with its speed but...

The horse would be traveling 6.25 km/hr

You simply take the overall travel (25km) and divide it by the total time (4hr)

You get 6.25km as your answer, meaning that every hour the horse traveled 6.25km every hour.

4 hours later the horse has reached 25km

43 is 120% of what number? 0.36 3.58 358.33 35.83

Answers

Answer:

The correct option is 4.

Step-by-step explanation:

It is given that 120% of a number is 43.

Let the number be x.

$x* (120)/(100)=43$

$x* (12)/(10)=43$

Multiply both sides by 10.

$x* 12=43* 10$

$12x=430$

Divide both sides by 12.

$x=(430)/(12)$

$x=35.8333333333$

$x\approx 35.83$

The required number is 35.83. Therefore the correct option is 4.

Jack bought two sweaters for $17.99 and a pair slacks for $25.50. Including a 5 1/2% tax, how much was his total purchase?

Question 5 options:

$64.86

$61.48

$52.99

$28.98

Answers

Answer:

(A) $90.23

(B) $64.86

Step-by-step explanation:

(A) Given, The cost of one skirt = $18.27

The cost of one shirt = $15.78, Then cost of two shirt = 2 × $15.78 =$ 31.56

and The cost of pair of shoes = $34.50

Thus, I have done total purchase of $18.27 + $31.56 + $34.50 = $84.33.

And, paying the tax of 7%

The total cost I spend = $84.33 × (100 + 7)% = $90.23

(B) Given, The cost of one sweater = $17.99, Then cost of two sweater = 2 × $18.27 =$ 35.98

The cost of one slack = $25.50

Thus, I have done total purchase of $35.98 + $25.50 = $61.48.

And, paying the tax of 5.5%

The total cost I spend = $61.48 × (100 + 5.5)% = $64.86
