Question

It takes Mr. Martin 12 minutes to drive his bus route without stopping to pick up any passengers. For each passenger stop, he estimates that 30 seconds is added to his travel time. On Tuesday, Mr. Martin spends 14 minutes driving his route.

Which equation can be used to determine the number of passenger stops, p, Mr. Martin had on Tuesday?
14 = 0.5p + 12

Answer 1

14 = 0.5p + 12

Explanation:

Answer 2

I found the missing choices. The choices are:
14 = 0.5p + 12
14 = 12p + 0.5
p = 0.5(14) + 12
p = 12(14) + 0.5

Given:
constant travel time. 12 minutes
30 seconds additional time per passenger
14 minutes - travel time on Tuesday.

Since 30 seconds is half the total seconds in a minute, it is equal to 0.50
The correct equation is: 14 = 0.5p + 12
