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
