Question 844247
A teacher lives at a distance of 2.6 km from her school.
(i) Calculate the time, in minutes, that she takes to walk from home to school if she walks at an average speed of 4 km/h.
time = distance/rate = 2.6 km/4 km/hr = 0.65 hrs. = 39 minutes
================================== 
(ii) If she arrives at school at 8.15 a.m. , at what time did she leave home?
8:15 - 39 minutes = 7:56 AM
==========================
