2. Ashley's older brother, Jamaal, is planning to ride his bicycle from Los Angeles to Washington D. C., a distance of 2,668 miles, in two months. Jamaal has decided that he will ride for three days and then rest on the fourth day. If he maintains this plan, and rides on 45 of the 60 days, what
is the minimum number of miles that Jamaal must ride each day with his new plan?
A. 55 miles
B. 60 miles
O
C. 65 miles
O
D. 70 miles

The correct answer is B. 60

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.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
