Question

Caden exercises daily by walking on a treadmill. He sets the machine so that he will walk at a steady rate of 3.6 miles per hour.

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


b. Use your equation to calculate the distance Caden will walk in 3/4 of an hour.


c. Use your equation to calculate how long it will take for Caden to walk 4.32 miles.

Answer 1

Answer: For this question, the answers are as follows:

a) d = 3.6t

b) 10.8 miles

c) 1.2 hours

Step-by-step explanation:

Part A: The slope of a line is y=mx+b

equation for this part would be : d=mt

plug in the value: d=3.6t

Part B: The value of t is 3 hours

Plug everything in: 3.6 (3)= 10.8 miles

Part C: The Distance given is 4.32 miles.

4.32 miles = 3.6 hours

then divide both sides by 3.6

you get t=1.2 hours

Hope this helped and didn't confuse you!
