Answer:
8 hours
Step-by-step explanation:
If Marvin's time for recreational activities is Y and he spent 2.8 hours which represents 35% of his time on recreational activities, this may be expressed mathematically as
35% * x = 2.8 hours
where x is the time at the recreational center
35x = 2.8 * 100
x = 280/35
= 8 hours
Answer:
Marvin spent 8 hours at the recreational center
Step-by-step explanation:
Marvin spent 2.8 hours which is 35% of his time at the recreational center playing ping pong. The time Marvin spent at the recreational center can be calculated below.
Let
The time he spent at the recreational center = a
He now spent 2.8 hours playing ping pong , the 2.8 hours he spent is 35% of the time he spent in the recreational center.
Therefore,
35% of a = 2.8
35/100 × a = 2.8
35a/100 = 2.8
cross multiply
35a = 280
divide both sides by 35
a = 280/35
a = 8 hours
Marvin spent 8 hours at the recreational center
