Question

A park is 1500 metres long and 750 metres wide.A cyclist has to take four rounds of this park. How much time will he take at the speed of 4.5km/h?​

Answer 1

Answer:

Step-by-step explanation:

To answer this question, we must first calculate the perimeter of the park.  

The park is in form of a rectangle.  

Perimeter of the rectangle = (Length +  Width)2  

This equals to: (1500 + 750)2  

= 2250 × 2 = 4500 m  

The perimeter of the park is 4500 meters.  

The Cyclist takes four rounds.  

Four rounds is equivalent to; 4500 × 4 = 18000 meters  

So, the cyclist covers a distance of 18000 meters.  

Since the speed is given in km/h, we convert this distance to kilometers.  

1km = 1000m  

so we have: 18000/1000 = 18 km  

Given speed and distance, the formula for getting time is:  

Time = Distance/Speed  

= 18/4.5 = 4 hours.
