Nabeel travelled to London by train, his journey was made up of two parts.

One train into York and then another train into London.

The first train departed at 07:05 and the journey lasted for 12 minutes.

The second train departed at 07:27 and the journey lasted for 122 minutes.

The total distance travelled was 197 miles.

What was Nabeel’s average speed for the entire journey in mph to 22 decimal places?



Answer :

Answer:

Step-by-step explanation:

To find Nabeel's average speed for the entire journey, we need to calculate the total time taken and then use the formula for average speed.

Calculate the total time taken for the journey:

Time for the first train journey: 12 minutes

Time for the second train journey: 122 minutes

Total time = 12 minutes + 122 minutes = 134 minutes

Convert the total time from minutes to hours (since speed is typically measured in miles per hour):

Total time in hours

=

134

 minutes

60

Total time in hours=

60

134 minutes

​

Total time in hours

=

2.23333

…

 hours

Total time in hours=2.23333… hours

Calculate the average speed using the formula:

Average speed

=

Total distance

Total time

Average speed=

Total time

Total distance

​

Given the total distance travelled was 197 miles, substitute into the formula:

Average speed

=

197

 miles

2.23333

…

 hours

Average speed=

2.23333… hours

197 miles

​

Average speed

≈

88.24486

…

 mph

Average speed≈88.24486… mph

Round the average speed to 22 decimal places:

Average speed

≈

88.24486104218362282846

…

 mph

Average speed≈88.24486104218362282846… mph

Therefore, Nabeel's average speed for the entire journey, rounded to 22 decimal places, is

88.24486104218362282846

88.24486104218362282846 mph.
