Elmo · Answer 1

Distance formula distance=speed*time

Giselle Barnett · Answer 2

60 mins = 1 h. 30 mins = 0.5 (1/2) h

before she speeded up, she had gone: s = t*v = 1h * 40 mph = 40 (m)

the length of the high way she drove: s = t*v = 0.5h * 70 mph = 35 (m)

the length of the way from your house to grandparents' house: 40+35=75 (m)
