#32/3# times

Andrew runs #= 4min#

Bryan runs #= 3min#

Total race runs #=36min#

Since its same Circuit that means its a Linear Equation..

How many times does bryan overtake andrew during the race??

Solution

Let the times Bryan overtook Andrew during the race be represented by #x#

#3 xx x + 4 = 36 -> "Statement"#

#3 xx x + 4 = 36#

#3x + 4 = 36#

Subtract #4# from both sides..

#3x + 4 - 4 = 36 - 4#

#3x = 32#

#x = 32/3#

Hence Bryan overtook Andrew during the race #32/3# times..
