Respuesta :

18 hours 770

770/18 average speed.

Answer:

The average speed for both days, while driving is 42.77 miles/hr.

Explanation:

Given that,

Distance first day = 500 miles

Distance second day = 270 miles

According to question,

The distance covered by the john in 10 hours = 500 miles

Next day ,

The distance covered by the john in 8 hours = 270 miles

We need to calculate the average speed for both days

Using formula of the average speed

[tex]v_{avg}=\dfrac{D}{T}[/tex]

Where, D = total distance

T = total time

Put the value into the formula

[tex]v_{avg}=\dfrac{500+270}{10+8}[/tex]

[tex]v_{avg}=\dfrac{770}{18}[/tex]

[tex]v_{avg}=42.77\ miles/hr[/tex]

Hence, The average speed for both days, while driving is 42.77 miles/hr.
