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
5/8 of an hour
Krissa will jog ( ) miles in
5/8 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.

Explanation:

Answer 2

Explanation:

A) We use this relation: Distance = time * speed ( speed or vitesse or rate)

So d= 3.4*t= 3.4t (miles)

B) If t= 5/8

then the distance d= 3.4* 5/8= 2.125 miles.

C) If the distance d= 5.44, we can find the time like:

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

so 5.44= 3.4*t or t = 5.44/3.4, t= 1.6 hours

Hope you understand it.
