Answer:

t<45 mins

Step-by-step explanation:

If to qualify you must finish in less than 45 minutes, this simply means your time has to be less than 45 so it would be t<45 mins. If it had said in 45 mins or less, it would say t is less than or equal to 45 but that's not what we have here.

ABCD ~ EFGH
vredina [299]

Answer:

FG = 20 in

Step-by-step explanation:

∵ EH = 60 in

∴ BC = 15 in

∴ 45/60 = 15/FG

∴ FG = (60 × 15) ÷ 45 = 20 in
