12 if im correct
Step-by-step explanation:
first we have to see that they are doing 1/8 of a mile per hour so if we divide 1.48 by 1/8 it should give us the time
first we convert 1/8 to a decimal which is .125 and we divide 1.48 by .125
giving us 11.84
since it is time, 11 hrs would be too little of a time so we need to round up to 12
