Question

determine the correct equation for the following verbal sentence;
the total distance traveled, d, at a constant speed of 45 miles per hour is the product of the speed and the number of hours traveled, h.
a. d = h + 45
b. d = 45h
c. $d = \frac{45}{h}$
d. d = 45 - h
please select the best answer from the choices provided
a
b
c
d

Explanation:

Step1: Recall distance formula

The formula for distance \( d \) when speed \( s \) is constant and time is \( h \) is \( d = s \times h \). Here, speed \( s = 45 \) miles per hour.

Step2: Substitute speed into formula

Substitute \( s = 45 \) into \( d = s \times h \), we get \( d = 45h \).

Answer:

B. \( d = 45h \)
