Answer:

it takes 196 seconds for completing 28 metres of race for person A

Step-by-step explanation:

Time Taken by B = 7 sec = 28 m

Time Taken by A = 28x7

28x7=196

196=196

Answer 2

Answer:

Step-by-step explanation:

1km=1000m

time taken to finish 28m race= 7 sec

                                1m race=7/28=1/4sec

time taken to finish 1000m race=1000/4=250sec=4min10sec

as A beats B by 7sec so,

250sec-7sec=243sec=4min3sec.
