Jack rode a bike through a new in the path shown at the right. If Jack took an average of 2 pictures per mile, how many pictures

Alex73 [517]

Answer:

Jack took 10 pictures on his bike ride.

Step-by-step explanation:

Given that:

Given measurements of sides are 3 miles and 4 miles

We will find the distance of the new route by using Pythagorean theorem.

$a^2+b^2=c^2$

(3)² + (4)² = c²

9 + 16 = c²

25 = c²

c² = 25

Taking square root on both sides

$\sqrt{c^2}=\sqrt{25}\\c=5$

The distance of new route = 5 miles

Picture taken per mile = 2

Picture taken on bike ride = 2*5 = 10 pictures

Hence,

Jack took 10 pictures on his bike ride.
