Answer:
11 cars =21/2 hours
Convert 21/2 hours to minutes
60minutes =1hour
2.5 hours =150mins
11cars=150 mins
1 car =1/11×150mins=
150/11=13 7/11mins

7/11×60secs =38secs
Answer =1car =13mins 38 secs
Step-by-step explanation:
J + 1/2= 3 9/14
convert 3 9/14 to improper fraction
J + 1/2= [(3*14)+9]/14
J + 1/2= 51/14
subtract 1/2 from both sides
J= 51/14 - 1/2
change both to common denominators (of 14 in this case)
J= 51/14 - 7/14
subtract numerators only
J= 44/14
simplify numerator and denominator by 2
J= 22/7
convert back to mixed number
J= 3 1/7
ANSWER: J= 3 1/7
