Answer:
298.36
Step-by-step explanation:
Let's assume that a month has four weeks.
If William made 400 miles by travelling only on Saturdays and Sundays and there were 4 weekends during the month, then he travels 400 / 4 = 100 miles during a weekend, which is 100 / 2 = 50 miles a day.
If Jason travels every weekday during the month and he does 500 miles, then he travels 500 / 20 = 25 miles a day.
It means that William travels more miles per day.
6.2 x 10^-3
Because when you add them together you get .0062 so you don't want anymore than one number to the left of decimal when in scientific notation therefore its 6.2 so you wanna move the decimal three spaces to the left to get .0062 therefore its 6.2x10^-3
