Answer:
Step-by-step explanation:
Distance on first journey =
Speed ×time=9×1000/60 ×35
(Speed converted to metre per minute by multiplying by 1000/60 )
=5250 m
Distance upon return journey
Speed ×time=9×1000/60 ×27 = 4050m
Distance on foot= distance on first journey -distance upon return journey
5250 - 4050 =1200 m= 1.2 km
