Mary can jog twice as fast as she can walk. She was able to jog the first 6 miles to her grandmother's house, but then she tired and walked the remaining 1 miles. If the total trip took 0.8 hours, then what was her average jogging speed?

MARY CAN WALK 7 MILES IN 0.8 HOURS ( 48 MINUTS )
SPEED = DISTANCE ÷ TIME
7÷0.8
= 8.75 Miles/ph
