Determine the cost of parking for each given amount of time. 5 minutes costs $ 1 hour costs $ 1 hour and 50 minutes costs $ 2 hours costs $ 2 hours and 1 minute costs $ 3 and a half hours costs $ ( it is $3 per hour or fraction of an hour)

5 minutes costs $0.25;

1 hour costs $3;

1 hour and 50 minutes costs $5.5

2 hours costs $6;

2 hours and 1 minute costs $6.05;

3 and a half hours costs $10.5

Explanation:

Given the cost of parking for each hour is $3

Therefore, 1 hour = $3

By principle of unitary method;

a)1 hour (60 minutes) = $ 3

   5 minutes =

     = $0.25

b)1 hour (60 minutes) = $3

   1 hour 50 minutes = 60+50 minutes = 110 minutes =

    = $5.5

c)1 hour (60 minutes) = $3

  2 hours (120 minutes) =

   = $6

d) 1 hour (60 minutes) = $3

  2 hours 1 minutes = 120 + 1 = 121 minutes =

  = $6.05  

e) 1 hour (60 minutes) = $3

   3 and half hours = (3× 60) +30 = 210 minutes =

  = $10.5

Therefore, 5 minutes costs $0.25; 1 hour costs $3; 1 hour and 50 minutes costs $5.5; 2 hours costs $6; 2 hours and 1 minute costs $6.05; 3 and a half hours costs $10.5
