Answer 1

Answer:

1.Speed of the car = (202/5) km/h. Time = (15/2) hours. Hence, distance it will cover in (15/2) hours = (202/5) × (15/2) = 303 km.

2.We know, area of a rectangle = length × breadth

⇒ Area of rectangular park

⇒ Area of rectangular park = 61 × 10

∴ Area of rectangular plot = 610 m
