Question

Kim drives 156 miles from Manchester to London.
She drives at an average speed of 60 miles per hour.
She leaves Manchester at 7:30 am
Does she arrive in London before 10:00 am​?

Answer 1

Answer:

No, he arrives at 10:06 am which is past 10:00 am.

Step-by-step explanation:

To find the arrival time we need to calculate the time taken to reach London.

Given the speed and the distance covered we can get the time using the formula below :

Time = Distance / speed

Distance = 156 miles

Speed = 60 miles per hour

We substitute this in the formula as follows :

Time = 156/60 = 2.6 hours

We can convert this to hours and minutes as follows :

6/10 × 60 = 36 minutes

Kim takes 2 hours 36 minutes.

The arrival time is :

7 : 30 + (2hrs 36 minutes) =

10 : 06 a.m

Kim arrives at 10:06 am which is past 10:00 am.

Answer 2

Answer:

Step-by-step explanation:

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.
