The average of their maximum speeds was 260 km/h. If doubled Malcolm’s maximum speed would be 80 km/h more than Ravi’s maximum s

san4es73 [151]

Answer:

Malcolm’s maximum speed is 200 km/h and and Ravi’s maximum speeds is 320 km/h.

Step-by-step explanation:

Let x and y are the maximum speeds ( in km / h ) of Malcolm and Ravi respectively,

Then according to the question,

$\frac{x+y}{2}=260$

$\implies x + y = 520-----(1)$

Again according to the question,

$2x = y + 80$

$\implies 2x - y = 80----(2)$

Equation (1) + equation (2),

3x = 600

⇒ x = $\frac{600}{3}$ = 200,

From equation (1),

200 + y = 520

⇒ y = 520 - 200 = 320

Hence, Malcolm’s and Ravi’s maximum speeds are 200 km/h and 320 km/h respectively.

27? i cant figure out her mistake can anyone help ?

expeople1 [14]

The mess up occurs in one of the first things she says. She first claims that 7^2 +25^2 = 24^2
Wait a minute... slow your roll there.
25 is the hypotenuse, or the longest side of the triangle AND opposite the right angle (but we aren't supposed to know that yet).
The Pythagorean Theorem holds that a^2 + b^2 = c^2, where a & b are the legs of the triangle & c is the hypotenuse. So, she got the formatting correctly, but she switched 24 & 25.
Hope this helps!
