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
14 = 12p + 0.5
p = 0.5(14) + 12
p = 12(14) + 0.5

Answer 1

the first one is the correct answer. 14=0.5p+12
the 14 represents the time driving the route, the 0.5p represents the 30 seconds times the passengers. the added 12 represents the time it takes without stopping.

Answer 2

I think your answer would be 14=0.5p+12. It is saying for every passenger, their is 0.5 seconds (30 seconds, since 0.5 is half of 1) added to the time it took to drive to his destination.

Hope I helped!
