Da Ming walks from his school to his house at a speed of 5km/h.he takes 20 minutes to reach home.what is the distance between his school&his house? Convert the time from minutes to hour and correct to 2 decimal places

20 min = 20/60 hrs = 1/3 hr
distance = time x speed
= (1/3)(5) = 5/3 or appr 1.67 km
