Doug travels 5 times as fast as Gloria. Traveling in opposite directions, they are 858 miles apart after 6.5 hours. Find their rates or travel.

Respuesta :

Distance = rate x time

Gloria = X mph

Doug = 5X mph

Where X is the rate of speed

And we have that they are 858 miles apart after 6.5 hours

6.5 X + 5( 6.5 X) = 858 mph

6.5X + 32,4X= 858 mph

39X = 858mph

X = (858mph)/39 = 22

5X = 110

So Gloria is traveling at 22 mph and Doug is traveling at 110 mph. This meand that Gloria rate of speed is 22 and Doug is 110
