the length of a rectangular field is twice it's breadth .Arun jogged around it 3 times and covered a distance of 5.4 km find the length and breadth of the feild

L= 0.6km b= 0.3km

Step-by-step explanation:

L = length b= breadth

L= 2 * b = 2b

he jogged around 3 times to cover 5.4 km

So, jogging around once would be (5.4/3) = 1.8 km which is the perimeter

perimeter of a rectangle is 2(L + b)

since the length is twice the breath, substitute 2b for L in the formula

perimeter = 2(2b + b) = 2(3b) = 6b

perimeter = 6b

1.8 = 6b

divide both sides by 6

b = 0.3km

since L = 2b, them L = 2 * 0.3 = 0.6km.

it's

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
