A cyclist rides her bike at a rate of 15 miles per hour. What is this rate in kilometers per hour? How many kilometers will the cyclist travel in 3 hours? In yourcomputations, assume that I mile is equal to 1.6 kilometers. Do not round your answers.

Answers

Answer:

The cyclist will have traveled 72 kilometers with-in 3 hours.

Step-by-step explanation:

1 mile (s) = 1.60934 kilometer(s)

15 miles = 24.1402// 24 kilometers

by 3 hours:

45 miles = 72/72.4205 kilometers

Final answer:

To convert the rate from miles per hour to kilometers per hour, multiply by 1.6. The cyclist will travel 72 kilometers in 3 hours.

Explanation:

To convert the rate from miles per hour to kilometers per hour, we multiply by the conversion factor. In this case, we multiply 15 miles per hour by 1.6 kilometers per mile to get 24 kilometers per hour. To find the distance traveled in 3 hours, we multiply the speed by the time. In this case, 24 kilometers per hour multiplied by 3 hours gives us 72 kilometers.

tamara and her mother plan to put a stone path and their garden each stone is 2/3 foot long they plan to use 7 stones that will be touching how long is the path write an equation to solve a problem explain your reasoning

Answers

its 4.50 because if you divide it will be 4 and 2 then with the 2 over 4 it is 4.5
Ok, so each stone is 2/3 ft long and there are 7 of them.  If we let path = P, then...

P = 2/3 x 7
P = 2/3 x 7/1
P = 14/3
P = 4 2/3 ft

So the path will be 4 2/3 ft long.
