A long session lasts 50 minutes.
Step-by-step explanation:
Let,
Duration of long session = x
Duration of short session = y
According to given statement;
3x+4y=270 Eqn 1
each long session lasts twenty minutes longer than the short session.
x = y + 20 Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 7
Putting y = 30 in Eqn 2
A long session lasts 50 minutes.

Answer:
Shane must have collect 911 cans.
Step-by-step explanation:
Assume;
Cans collected by Shane = x
So,
Cans collected by Abha = x+178
Inequality
Cans collected by Shane + Cans collected by Abha ≥ 2,000
x + x + 178 ≥ 2,000
2 x ≥ 2,000 - 178
2 x ≥ 1,822
x ≥ 911
Shane must have collect 911 cans.
