Question

It takes a gardener 45 minutes to dig a flower bed of area 7.5m square. if he digs at the same rate, how long does he take to dig 9m square?​

Answer 1

Answer:

54m

Step-by-step explanation:

Time taken by gardener to dig a 7.5 m^2 flower bed = 45 minutes

.: Let the time taken to complete 9m^2 flower bed be x.

.: 45 minutes = 7.5m^2  

x = 9m^2

By cross multiplication

45×9 = x

7.5  

.: x = 54

Therefore it takes 54 minutes for the gardener to dig a flower bed of 9m^2.
