Answer:
1 7/10 hours more

Amount of time Mike spent = 3 4/5hrs
Amount of time Isela spent = 2 1/10 hours
To determine the number of hours Mike spent more than Isels, we will ake their hours difference
3 4/5 - 2 1/10
Convert to improper fraction
19/5 - 21/10
Find the LCM
= 2(19)-21/10

= 17/10
= 1 7/10 hours
Hence Mike spent 1 7/10 hours more tha Isela
