Answer: 2t - 20

Step-by-step explanation:

Jojo spends t minutes doing homework.

He then spends 20 minutes less than twice that amount of time doing homework.

For homework therefore, let us breakdown the time spent:

Spends twice the amount of time = 2t
Spends 20 minutes less than twice = 2t - 20

When doing homework, Jojo therefore spends:

= 2t - 20
