Marta exercise 30 minutes each day. Greg exercise 40 minutes each day. How many more minutes does Greg exercise than Marta in a month that has 31 days?

Greg exercises for 310 minutes more than the amount of time Marta exercises

Step-by-step explanation:

The expressions for the total number of minutes each exercise in a month is as follows;

Total number of minutes in a month=Number of minutes per day*number of days in a month

For Marta;

Number of minutes per day=30

Number of days in a month=31 days

replacing;

Total number of minutes in a month = (30*31) = 930 minutes

For Greg;

Number of minutes per day=40

Number of days in a month=31

Total number of minutes in a month = (40*31) = 1,240 minutes

To get how many more minutes Greg exercises in a month than Marta;

(Total number of minutes in a month Greg exercises-Total number of minutes Marta exercises)

where;

Total number of minutes in a month Greg exercises=1,240 minutes

Total number of minutes Marta exercises=930 minutes

replacing;

(1,240-930) = 310 minutes

Greg exercises for 310 minutes more than the amount of time Marta exercises
