Question

a park is 1500 metres long and 750 metres wide a cyclist has to take 4 rounds of The Spark how much time will take to speed at the speed of 4.5 km per hour ​

Answer 1

Answer:speed=distance/time

So

Distance =1500×2+750×2

=4500

Speed = 4.5 km/h

So sub the values

Time=4500×4rounds/4.5

Time=18000/4.5

Time=4 hours

Step-by-step explanation:

Answer 2

The cyclist takes 4 hours to complete this task

Explanation:-

DATA:

Length=1500m

Width=750m

Speed=4.5km/h

Time=t=?

SOL:-

The cyclist has to take 4 rounds and find out the time.

Perimeter= ( length + Width) x 2

Perimeter = (1500 + 750) x 2

Perimeter = 4500m

Total distance covered by the cyclist = 4500 x 4 = 18000m

Total distance in Km = 18000/1000 = 18.

So,  

Time  = Distance in Km / Speed.

Time = 18 / 4.5

Time = 4h
