(a) An important achievement in the history of track running occurred on May 6, 1954, when an Englishman, Roger Bannister, became the first person to run a mile in less than 4 minutes. What is the average speed of a person who runs one mile in exactly 4 minutes in miles per hour?

the thermometer is precise but not accurate

step-by-step explanation:

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
