Question

Ravi jogs around a square park of side 900 m while Kumar jogs around a rectangular park of length 800 m. Both have the same jogging speed. If in 1-hour Ravi completes 4 rounds of the park and Kumar completes 3, find the breadth of the rectangular park

Answer 1

Answer:

breadth =1600m=1.6km

Step-by-step explanation:

perimeter of Ravi's square park =4×length of one side

d1 =4×900=3600m

perimeter of Kumar's rectangular park=2(l+b)

d2 = 2( 800+b) = 1600+2b

given that both of them have same speed

d1/t1 = d2/t2

after 1 hr ravu had passed 4 rounds and Kumar had passed 3 rounds

4(d1/1hr) = 3(d2/1hr)

4d1=3d2

4(3600) =3( 1600+2b)

14400 = 4800+ 6b

6b = 14400 - 4800= 9600

b = 9600/6= 1600

b=1600m or 1.6km
