Question

30. Shelby walks at a constant rate. The equation that represents this
relationship is d= 4t, where d is the distance in miles and t is the
time in hours.
a. What does the coefficient 4 tell you about Shelby?
b. Make use of structure. What question is answered by the
equation d=4(32)?

Answer 1

Answer:

Step-by-step explanation:

In order for 4*t to equal d, the 4 has to represent a rate with respect to time because the multiplication between them will cancel the time unit. We know this because of the formula d = rt with 'r' being rate

a: 4 is the rate at which Shelby walks, 4 miles per hour

b: T is replaced with 32, so the expression tells us the distance Shelby travels in 32 hours at a rate of 4 miles per hour
