Un repartidor de comida va a entregar dos pizzas en el mismo viaje. La primera pizza se encuentra a 40 km al norte de la tienda, mientras que la segunda se localiza a 100 km al sur de la tienda. El repartidor bate su récord personal al llegar de la primera a la segunda casa en 10 s. ¿Qué velocidad lleva el repartidor?

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48

step-by-step explanation:

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
