Question

Kim drives 156 miles from rotherham to london. She drives at an average speed of 60 miles per hour. She leaves rotherham at 7:30 AM does she arrive in london before 10:00am

Answer 1

Answer:

She does not arrive at London before 10:00am

Step-by-step 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:

$60 = \frac{156}{Time}$

Make Time the subject

$Time = \frac{156}{60}$

$Time = 2.6$

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

Answer 2

Answer:

156/60= 2.6 hours.  

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

9:36 is when Kim won't reach London, so no

2.6 hours which is greater than 2.5 hours.
