The area of rectangular field is 3584m square and its length is 64m. A boy runs around the field at the rate of 6km/h. How long will be take to go 5times around it.
A = L x W
You know A and L, solve for W.
Perimeter = 2L + 2W. Substitute and solve for perimeter.
dustabce boy runs is 5 x perimeter= ?
6 km/hr = 6000 m/hr.
distance = rate x time. You know the rate and distance, substitute and solve for time in hours.
To find out how long it will take for the boy to run around the field 5 times, we need to calculate the distance around the field and divide it by the speed of the boy.
First, let's find the width of the rectangular field by dividing the area by the length:
Width = Area / Length = 3584 m² / 64 m = 56 m
Now, let's calculate the perimeter of the rectangular field (distance around the field):
Perimeter = 2 * (Length + Width) = 2 * (64 m + 56 m) = 2 * 120 m = 240 m
Since the boy is running at a speed of 6 km/h, we need to convert the distance (perimeter) into kilometers:
240 m = 0.24 km
Now, to find the time it will take for the boy to run around the field 5 times, we can divide the total distance by the speed:
Time = Total Distance / Speed = (5 * 0.24 km) / 6 km/h
Simplifying this equation, we can cancel out the "km" units:
Time = (5 * 0.24) / 6 hours
Therefore, it will take the boy ((5 * 0.24) / 6) hours to run around the field 5 times.
