Answer:
1 min .234 sec
Explanation:
3 min 25 sec to fill 75 litre gas tanks
how many min will fill 55 lite gas
lets convert 3 min 25 sec to seconds
3 min = 3 × 60 sec
60 + 25 = 85 sec
85 sec = 75
x sec = 55
cross multiply
75x = 85 × 55
75x = 4675
x = 4675/75
x = 62.33333333 sec
convert (62.3333333) sec to min
62.34 ÷ 60 = 1 min 2.34 sec
