Jim travels
6 times faster than Brenda. Traveling in opposite directions, they are
392 miles apart after
3.5 hours. Find their rates of travel.
let x= brenda's rate of travel
6x=jim's rate of travel
travel time*rate=distance
3.5x+3.5*6x=392
3.5x+21x=392
24.5x=392
x=16mph
6x=96 mph
brenda's rate of travel=16 mph
jim's rate of travel=96 mph
