Answer:
Option 2: 14.06 minutes
Step-by-step explanation:
For the first scenario, we will convert the minutes into hours first to get all the quantities in same unit
So,
15 minutes = 1/4 hours = 0.25 hours
Speed = 7.5 miles per hour
Now using the speed, distance and time formula
Speed = distance/time



Distance = 1.875 miles
So the distance for 1st day is 1.875 miles.
For next day
Speed = 8 miles per hour
Distance = 1.875
So,




Converting the hours into minutes will give
0.234375 * 60 min = 14.0625 minutes
Rounding off to two decimals = 14.06 min
So 2nd option is correct..
