last week juan worked 20.5 hours this week you breaks 1.5 hours as many hours as he did last week how many hours did one work this week

if i understood correctly, this problem is asking to multiply the two given numbers.

20.5 * 1.5 = 30.75

30.75 hours = 30 and 3/4 hours = 30 hours and 45 minutes (i believe)
