Which of the following equations represents the total distance in miles, D, that it took the bus to travel in t hours, if the bus was driving at a rate of 30 miles per hour?
Responses
A t = 30Dt = 30 D
B D = 30tD = 30 t
C
D = 30
tD = 30 t
D
t = D
30
The correct equation would be:
D = 30t
The correct equation that represents the total distance in miles, D, that the bus traveled in t hours is option B: D = 30t.
To understand why this is the correct equation, we need to know that distance is calculated by multiplying the rate of speed by the time traveled.
In this case, the rate of speed of the bus is 30 miles per hour. And the time traveled is t hours. So, to find the total distance traveled, we multiply the rate of speed (30) by the time traveled (t).
Hence, the equation that represents the total distance D is D = 30t.
The correct equation is B.
D = 30t
