Gre4nikov [31]

Answer:

Average speed = 68 mph

Explanation:

Given that,

Total distance traveled by the family, d = 340 miles

The family traveled 5 hours southeast.

We need to find her average speed. The speed of an object is given by the total distance covered divided by time taken. So,

$v=\dfrac{d}{t}$

Put all the values,

$v=\dfrac{340}{5}\\\\v=68\ mph$

So, her average speed is equal to 68 mph.
