Krissa exercises daily by walking. She aims to walk at a steady rate of 3.4 miles per hour.

Part A

If t represents time in hours and d represents distance in miles, write an equation that models the relationship between these variables.

d=

Part B

Use your equation to calculate the distance Krissa will jog in 58 of an hour

Krissa will jog

miles in 58 of an hour.

Part C

Use your equation to calculate how long it will take for Krissa to walk 5.44 miles.

It will take Krissa

hours to jog 5.44 miles.

a. 3.4t (miles)

b. 2.125 miles

c. t = 1.6 hours

Step-by-step explanation:

A) We will use the relation:

Distance = Speed × Time

Distance= 3.4 × t

= 3.4t (miles)

B) If t= 5/8

Distance d= 3.4 × 5/8

= 3.4 × 0.625

= 2.125 miles.

C) If the distance d= 5.44,

Time will be:

d= 3.4t, and we know that d=5.44

Therefore, 5.44 = 3.4t

t = 5.44/3.4

t = 1.6 hours

square root

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
