Answer 1

Step-by-step explanation:

Given s = t + 220/30 ... (i)

and s = t + 325/39 ... (ii)

Solving (i) and (ii), we get

39(t + 220) = 30(t + 325)

39t + 8580 = 30t + 9750

9t = 1170

t = 130 m

Put in (i), we get

Speed = 130 + 220/30

= 350/30

= 11.66 m/sec

S = 3600 × 11.66/1000

hope it's help you...❤✌

Answer 2

Step-by-step explanation:

Given

s = t + 220/30 ... (i)

and s = t + 325/39 ... (ii)

Solving (i) and (ii), we get

39(t + 220) = 30(t + 325)

39t + 8580 = 30t + 9750

9t = 1170

t = 130 m

Put in (i), we get

Speed = 130 + 220/30

= 350/30

= 11.66 m/sec

S = 3600 × 11.66/1000
