Answer 1

Answer:

A) she spent about 3.5 hours longer sleeping than watching T.V.

B) percentage of the day did she spend on playing sport = 15%

Step-by-step explanation:

A.

from the data given in the graph we can clearly say that Tammy spent nearly 8.5 hours in sleep

and she spent approximately 5 hours watching T.V.

Thus,  she spent about 3.5 hours longer sleeping than watching T.V.

B

percentage of the day did she spend on playing sport can be calculated by

$% of playing sport = time of playing sport \div total time$$percentage of the day playing sport = time spent on playing sport \div total time$

total time spent on playing sport is approximately 2.5 hours

total time = 24 hours

thus,

$percentage\:of\:the\:day\: playing\:sport = (2.5\div24) \times 100$

= 11 % (approximately)
