Explanation:

The given values are:

Force,

F = 306 N

Drive,

D = 125 miles,

i.e.,

  = 201168

meters

As we know,

The work done will be:

= [tex]F\times S[/tex]

On substituting the given values, we get

= [tex]306\times 201168[/tex]

= [tex]61557408 \ J[/tex]

On converting it in "MJ", we get

= [tex]61.557\times 10^6 \ J[/tex]

= [tex]61.557 \ MJ[/tex]
