Math: distance,rate,time
Jamila left home on her bike at 11:00 AM traveling at 12 km/h. At noon, her sister Tamantha set out after her following the same route. If Tamantha's motorcycle traveled 28km/h, what time did Tamantha overtake Jamila?

Math: distance,rate,time
Jamila went 12t km, (remember D=R*T) Tamantha went 28(t-1) , she went 1 hour less than Jamila But when she overtakes her sister, they went the same distance, so 28(t-1_ = 12t 28t - 12t = 28 16t=28 t = 1.75 which is 1 hour and 45 minutes so Tamantha caught up with her sister 12...

Math: Distance and Midpoint
Three points on the edge of a circle are (-220, 220), (0, 0), and (200, 40), where each unit represents 1 foot. What is the diameter of the circle to the nearest 10 feet? I know the answer is supposed to be 550 ft, but I keep coming up with the wrong answer. I found the ...

Math: Distance and Midpoint
Alas, things have gone awry. The slope of the line from (-220,220) to (0,0) is -1. So, the slope of the perpendicular bisector (pb) is 1. The equation of the pb is thus (y-110) = (x+110) y = x + 220 The slope of the line from (0,0) to (200,40) is 40/200 = 1/5. The pb slope is ...

math word problem
I have to assume that they start in the same place, running in opposite directions. Running in the same direction, you get the time for Andy to "lap" Kate: Va*100 - Vk*100 = 400 meters which means Va - Vk = 4 m/s Running in opposite directions, they start out 400 meters (one ...

Problem is flawed - Math
The data given for the problem contradicts each other and does not make sense. drwls pointed out correctly that we would get 4 congruent right-angled triangles, the hypotenuse would be 10, one side is 3.5, let the other side be x x^2 + 3.5^2 = 10^2 x = √87.75 or appr. 9....
