Last year, there were 148 pies baked for the bake sale. this year, there were c

We need to find the number of pies baked in years 1 and 2.

There were 148 pies baked in year 1.

There were pies baked in year 2.

Rearrange the terms so the variable is first.

Volume of the prism is given by:
V=(base area)*(height)
thus:
base area=1/2(a+b)*h
=1/2(1.4+0.6)*2
=2 m²

Thus the volume will be:
V=2*1
V=2 m³

Volume after 30 min:
V=2×(0.8)
V=1.6 m³

Rate of emptying the tank is:
(2-1.6)/30=1/ 75 m³/min
time taken to empty the tank:
time=volume/rate
time=2/(1/75)
=150 min
