Question

A rectangular field is measured 290 m by 210 m. How long will it take for a girl to go two times the field, if she walks at the rate of 1.5 m/sec?
​

Answer 1

Answer:

1333.3sec

Step-by-step explanation:

l=290m

b=210m

P=2(l+b) units

P=2(290+210) m

P=2×500 m

P=1000m

distance for 2 rounds =2×1000=2000m

S=D/T

T=D/S

T=2000/1.5

T=20000/15

T=4000/3

T=1333.33 sec
