_______________70__________(___)______d
TOTAL______________________10________2d

Calculate the missing time.

_______________speed_______time______distance
_______________60___________x_________60x
_______________70__________10-x______70(10-x)
TOTAL______________________10________d

The equation to find from the tabulated information is d=60x%2B70%2810-x%29
-
d=60x%2B700-70x
highlight%28d=700-10x%29
