Question

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

Answer 1

Answer:

• 1500-750
• 1500-750750-1500
• 1500-750750-150010-1

Answer 2

the Park is a form of rectangle

perimeter of a rectangle=2(l+w)

the equals to ( 1500 + 750) 2

=2250 × 2 =4500m

perimeter of a Park is 4500 meters.

A cyclist has to take four rounds

four rounds is equivalent to: 4500 × 4 = 18000 meters.

so the cyclist coveres the distance of 18000 meters.

since the speed is given in km/h, we convert this distance to kilometer

1km = 1000 meters

time = distance/speed

=18/4.5 = 4hours
