If josh jogs an average of 8 miles per week for three weeks how many miles will he need to jog during the fourth week to bring his four week average to 10 miles per week?

To find out how many miles Josh needs to jog in the fourth week to average 10 miles per week over four weeks, we can use the formula: Total distance = Average distance * Total weeks. Josh's total distance for the first three weeks is 8 miles/week * 3 weeks = 24 miles. To average 10 miles per week over four weeks, he needs to cover a total of 10 miles/week * 4 weeks = 40 miles. Therefore, in the fourth week, Josh needs to jog 40 miles - 24 miles = 16 miles to achieve an average of 10 miles per week over four weeks.
