No, she will not arrive  London before 10:00 am.

Step-by-step explanation:

It is given that:

Kim drives 156 miles from Rotherham to London.

She drives at an average speed of 60 miles per hour.

i.e. in one hour she drives 60 miles.

Hence she covers 1 mile in 1/60 hours.

Now she has to travel 156 miles.

i.e. it takes her:

156/60 hours=2.6 hours.

i.e. it takes her 2 hours and 36 minutes to reach from Rotherham to London.

(

since 0.6 hours=36 minutes.

As 1 hour= 60 minutes.

so, 0.6 hours=0.6×60=36 minutes ).

Hence, if she start from Rotherham at 7:30 am.

Then she will reach London at:

7:30+2.6=10:06 am.

Hence, she will reach London after 10 am.

the answer is b
