Knowing that electricity+travels at approximately one+foot+per+1.5+nanoseconds , we can write it as:
1ft%2F1.5ns


Since one foot=0.000189394ml and 1.5+_nanoseconds=0.0000015ms, we have:
electricity travels at 0.000189394ml+%2F0.0000015ms
Now we need to see how far electricity travels in 7ms:

%280.000189394ml+%2F0.0000015ms%29%2A7ms.....cancel ms
0.001325758ml%2F0.0000015=883.84ml
