The driving distance between London and Manchester is 195 miles. If a coach that is 50 mph leaves Manchester at 15:30pm, what time will it arrive at london

It will arrive at 19:24 pm at london

Step-by-step explanation:

Distance between London and Manchester = 195 miles

Speed of coach = 50 mph

Time taken to cover the given distance =

Time taken to cover the given distance =

1 hour = 60 minutes

0.9 hours =

So,Time taken to cover the given distance = 3 hours 54 minutes

He left at 15:30 pm

Total time taken =  3 hours 54 minutes

It will arrive at time =19:24 pm

Hence it will arrive at 19:24 pm at London

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
