a student took 18 minutes to walk from home to school.

a) given that he arrived in school at 07 05,find the time at which he left home?

b)given also that he walked to school at an average speed of 4 km/h,calculate how far he had to walk?

Answer provided by our tutors

a) is 6:47

b) However, begin by changing the 18 minutes into hours:

18min * 1hr/60min

= 18/60

= 3/10 hour

.

distance = 3/10 * 4

distance = 3/5 * 2

distance = 6/5 km

or

distance is 1.2 km
