Question

3 Imran
cross a
45kilometer long bridge
in 3.5 minutes find the speed of his
cycle?​

Answer 1

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

=>9000x10/7

=>12857.14

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

12.8km per hour

Answer 2

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
