A lap around a school track equals 1/4 of a mile. Caleb runs 4 laps on Monday and 6 laps on Wednesday. How many more miles does Caleb need to run Thursday if he wants to run 6 miles total?
A. 1 1/2
B. 2 1/2
C. 3 1/2
D. 4 1/2
(4*1/4) + (6*1/4) + X miles = 6
To find the answer, we need to figure out how many miles Caleb runs on Monday and Wednesday combined and subtract that from the 6 miles he wants to run.
First, we find the total number of laps Caleb runs on Monday and Wednesday:
On Monday, Caleb runs 4 laps.
On Wednesday, Caleb runs 6 laps.
Therefore, Caleb runs a total of 4 + 6 = 10 laps on Monday and Wednesday.
Since 1 lap equals 1/4 of a mile, we can find the total number of miles Caleb runs by multiplying the number of laps by 1/4:
10 laps x 1/4 mile/lap = 10/4 miles = 2.5 miles
Next, we subtract the total miles Caleb has already run from the 6 miles he wants to run:
6 - 2.5 = 3.5 miles
Therefore, Caleb needs to run an additional 3.5 miles on Thursday to reach his goal.
The correct answer is C. 3 1/2
Caleb runs a total of 4 laps + 6 laps = 10 laps on Monday and Wednesday.
The distance covered in 10 laps is 10 laps * 1/4 mile per lap = 2.5 miles.
To reach a total of 6 miles, Caleb still needs to run 6 miles - 2.5 miles = 3.5 miles.
Therefore, the answer is C. 3 1/2.
