The correct answer is B. 60
Step-by-step explanation:
To cover the distance between Los Angeles and Washington, Jamaal needs to travel 2668 miles in 45 days considering he will rest every fourth day and therefore there are 15 days in which he will not ride his bike (60 ÷ 4 =15). Now, to find the minimum distance he needs to travel every day, simply divide the total distance into the total days he will travel 2688 ÷ 45 = 59.7333 which can be rounded as 60 miles per day. According to this, the correct answer is B.
