if a park is 1500 metre long a nd metre long and 750 metre wide a cyclist has to take for round of this Park how much time will it take in the speed of 4.5 km per hour
Answers
The cyclist will take 4 hrs with a speed of 4.5 km per hour to take 4 rounds of the park.
Step-by-step explanation:
Dimensions of the park:
Length, L = 1500 m = 1.5 km
Breadth, B = 750 m = 0.75 km
Since the cyclist is taking rounds of the park so in order to find the distance covered in 1 round we have to find the perimeter of the park.
∴ The perimeter of the park is given by,
= 2* [L+B]
= 2 * [1.5 + 0.75]
= 2 * 2.25
= 4.5 km ← distance covered by the cyclist in 1 round
∴ The total distance covered by the cyclist in taking 4 rounds of the park, = 4 * 4.5
= 18 km.
The speed of the cyclist is given as 4.5 km/hr
Thus,
The time taken by the cyclist to cover a distance of 18 km with a speed of 4.5 km/hr is,
= Distance/Speed
= 18/4.5
= 4 hrs
