The distance between Bob's home and his school is 2.5 miles.
What is speed?
Speed is the distance covered in unit time.
Speed of Bob = 3mph
Speed of his sister = 12mph
Distance between Bob's home and his school = distance covered by bob in 10 minutes + distance covered by his sister in 10 minutes.
Distance covered by Bob in 10 minutes = 3*10/60 = 0.5 mile.
Distance covered by His sister in 10 minutes = 12*10/60 = 2 miles.
