Step-by-step explanation:Since Speed=Distance by time

Here Distance is in km

whereas time in minutes

hence the first step is to change Km into m

Therefore,

1 km=1000m

45km= 45000m

Therefore

Speed = 45000/35/10

=>45000 x10 /35

=>9000×10/7

=>12857.14

Therefore the speed will be 12,857 m per minute which will be

12.8km per hour

Answer:7/120

Step-by-step explanation:Given,

Distance = 45 km

Time = 3.5 min = (3.5*1/60)hr

Therefore,

speed = distance / time

speed = 45/(3.5*1/60)

speed = 45*60*10/35

speed = 5400/7
