Answer 1

Answer:

No. Kim arrives to London at 10.06 a.m. which is after 10.00 a.m.

Step-by-step explanation:

Distance = 156 miles

Average Speed= 60 m/h

Time= D ÷ S= 156÷60

=2.6 h

Convert the 2.6 h into minutes

2.6 × 60 = 156 mins = 2 h 36 min

--------------------->>

7.30 a.m.= 7 h 30 min

Time Kim reaches London= 2 h 36 min + 7 h 30 min=

9 h 66 min= 10 h 06 min

10 h 06 min can be written as --> 10.06 a.m

Hope it helps

Answer 2

Distance driven by Kim from Rotherham to London = 156 miles

Her average speed = 60 miles/h

We know that :

$time = \frac{distance}{speed}$

Which means, the time Kim takes to go to London :

$= \frac{156}{60}$

$=\color{plum}\bold{ 2.6 \: hours}$

Thus, she would have taken 2 hours 36 minutes to reach London.

Time in which she would have reached London = 10:06 am

Therefore, no Kim doesn't arrives in London before 10:00 am.
