Answer:
He must study for at least 7.5 hours each week
Step-by-step explanation:
Here, we want to know the number of hours that Mr Smith must study each week
From the question, we are told that he must study a minimum of 60 hours total over the course of the 8 weeks
The number of hours he must study each week will be 60/8 = 7.5 minimum number of hours each week
$3.55 + $0.65 + $2.45 = $6.65
The total cost is $6.65.
Speed = distance / time
Speed = 120 / 33
Speed = 3.64 miles per hour
