Best ResponseYou've already chosen the best response.0500t = 200t+800 300t=800 t=8/3 d=500t=500(8/3)=1,333 1/3miles

Best ResponseYou've already chosen the best response.0why do you give up? You found out that in 2 2/3 hours the jet will catch the other plane, right?

Best ResponseYou've already chosen the best response.0Stop saying "can't". You got the time right. If you go 50 miles in one hour, how far will you go in 2 hours?

Best ResponseYou've already chosen the best response.0I know but I'm on A bus traveled on a level road for 3 hours at an average speed 20 miles per hour faster than it traveled on a winding road. The time spent on the winding road was 4 hours. Find the average speed on the level road if the entire trip was 188 miles.

Best ResponseYou've already chosen the best response.0This time it tells you the total of the two distances so write and solve the equation that says the sum of the distances is 188

Best ResponseYou've already chosen the best response.0So the sum is 4r + 3(r+20)

Best ResponseYou've already chosen the best response.0\[4r+3(r+20)=188\] \[4r+3r+60=188\] \[7r+60=188\] \[7r=128\] \[r=\frac{128}{7}=18 \frac{2}{7}\]
