Respuesta :

Answer:

Josh played guitar for a longer time

Step-by-step explanation:

Josh plays band for 80% of the total band time i.e 90 minutes

Time in minutes for which Josh played the guitar

[tex]= \frac{80}{100} * 90\\= 72[/tex]

Thus, Josh played the guitar for 72 minutes.

Time left for Alice to play guitar

[tex]= 90 - 72 = 18[/tex] minutes.

Hence, we can say that Josh played guitar for a longer time
