AB = BD = 10cm

Now using the Pythagorean theorem:

26^2 = 10^2 + BC^2

Simplify:

676 = 100 + BC^2

Subtract 100 from both sides:

576 = BC^2

Take the square root of both sides:

BC - sqrt(576)

BC = 24 cm

andre rode his bike at a constant speed he rode 1 mile in 5 minutes which of these equations represents the amount of time in mi

Alex777 [14]

We are given

Andre rode his bike at a constant speed he rode 1 mile in 5 minutes

Firstly, we will find constant speed

In 5 minutes , distance travelled =1 miles

so, we get speed

$v=\frac{1}{5} mile/min$

Let's assume T is time in minutes

D is the distance in miles

we know that

$Time=\frac{Distance}{speed}$

so, we can plug value

and we get

$T=\frac{D}{\frac{1}{5} }$

so, we get

$T=5D$ ...............Answer
