Mr. Jones jogs the same route each day. The amount of time he jogs is inversely proportional to his jogging rate.

What option gives possible rates and times for two of his jogs?

 

4 mph for 2 hours and 3 mph for 3 hours

3 mph for 2 hours and 4.5 mph for 3 hours

4 mph for 3 hours and 6 mph for 2 hours

4 mph for 3 hours and 6 mph for 4.5 hours

4 m/hr x 2 hr = 8 m      3 m/hr x 3 hr = 9 m      8 m does not equal 9 m     Nope ...not this one

 

Continuing.....

.....

 

.....

 

 

4 m/hr x 3 hr = 12 m   6 m/hr x 2 hr = 12    12 = 12     This one !
