Answer:
luke spent 200 minutes napping.
Step-by-step explanation:
the total time span spent by him in the above four activities rounded to nearest 10 :-
=》70 + 60 + 130 + 40
=》300 minutes,
and car trip was of 500 minutes, so total time spent by him sleeping is :-
=》500 - 300
=》200 minutes
B.) About 200 minutes napping
74+56+128+38=296
500-296=204
204 is about 200
Is there a picture to find the answer?
-x+20=31
