Answer 1

156/60= 2.6 hours.

2.6 hours is 156 minutes (2 hours, 36 minutes).

2.6 hours which is greater than 2.5 hours.

Answer 2

She does not arrive at London before 10:00am

Explanation:

Given

`Distance = 156\ miles`

`Departure =07:30am`

`Speed = 60mph`

Required

Determine if she arrives at London before 10:00 am

Using:

`Speed = Distance/Time`

We calculate the time spent on the journey.

So, we have:

`60 = (156)/(Time)`

Make Time the subject

`Time = (156)/(60)`

`Time = 2.6`

This means that, she travels for 2.6hour from Rotterdam to London.

Her Arrival Time is:

`Arrival=Departure + 2.6hours`

`Arrival=7:30am+ 2.6hours`

`Arrival=10:10am`

This implies that she does not arrive at London before 10:00am
