I WILL GIVE BRAINLIEST

Mathematics
1 answer:
Ber [7]3 years ago
4 0

Answer:

The answer is 450

Step-by-step explanation:

I got this equation:

x- the speed in which the turtle walks

5x+5(x+10)=4.5x+150+x*(150)/(x+10)

I got x=40, x=-50/11, but you can't have negative speed, so the turtle's speed is 40 meters per hour. After that, I just plugged in x onto one of the expressions and got 450.

So, after plugging them in, here's what you get:
