Question

You drive to Atlanta. You travel 4 hours at a

Answer 1

Answer:

It will take you 6 hours to get back home

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed of first leg of the trip = 60 mph

Speed of second leg of the trip = 40 mph

Time of the first leg of the trip = 4 hours

Time of the second leg of the trip = x hours

2. When you return home, you  drive slow. How long will it take to get back  home?

For answering the question, we will use the Inverse Rule of Three because the less speed you drive the more time it takes you to finish the trip, as follows:

Speed       Time

60 mph       4 hours

40 mph       x hours

40x = 60 * 4 (Inverse Rule, not Direct Rule)

40x = 240

x = 240/40

x = 6

It will take you 6 hours to get back home
