A steam shovel excavates 2 cubic yards every 40 seconds. At this rate, the amount excavated in 45 minutes is:

by

A) 95 Cu Yd
B) 275 Cu Yd
C) 135 Cu Yd 
D) 1250 Cu Yd

🧠 Explanation (Math):

Given: Rate = 2 cubic yards per 40 seconds; time = 45 minutes
Step 1: Convert time to seconds ⇒ 45 × 60 = 2700 s
Step 2: Rate = 2/40 = 0.05 cu yd/s
Step 3: Amount = 0.05 × 2700 = 135 cu yd
Final Answer: 135 Cu Yd
