Total distance from their home to school is 2 miles.
Peter covered this distance in 27 minutes yesterday. Since the rate of walking is the same today, Peter will arrive in school in 27 minutes today.
Juan covered 1 mile in 11 minutes yesterday. This means she will cover 2 miles in 22 minutes. Since the rate(speed) of walking of Jaun is also same as that of yesterday, Juan will reach the school in 22 minutes.
