It is 3.67 miles to your grandparents’ home.

If you can walk 4 miles in one hour, how long will it take for you to walk to your grandparents’ home? Express your answer in decimal hours and then convert the time to minutes (to the nearest minute).

To find the amount of time, take the distance and divide by the rate. The answer will be in hours.
Notice that the distance to your drandparents' home is less than 4 miles, so it will take less than one hour.
3.67 miles / 4 miles/hour = 0.9175 hours
To change this into minutes, multiply by 60, the number of minutes in one hour:
0.9175 hours x 60 minutes/hour = 55.05 minutes, which rounds to 55 minutes.
If you are interest in numbers, you might like to read the following:
2/3 = .6666666... which rounds to .67
So 3.67 miles might actually mean 3 2/3 miles.
If it does: (3 + 2/3) / 4 x 60 = exactly 55 minutes
