Question

Deandre downloaded 8 apps onto his tablet in 12 seconds. At this rate, how many apps could he download in one minute?

Answer 1

Answer:   40

Step-by-step explanation:

Given : Deandre downloaded 8 apps onto his tablet in 12 seconds.

By using UNITARY METHOD, the number of apps he download in one seconds will be :-

$\dfrac{8}{12}=\dfrac{2}{3}$

Also, 1 minute = 60 seconds

At this rate, the number of apps he can download in 60 seconds will be :-

$\dfrac{2}{3}\times60=40$

Hence, the number of apps he can download in one minute = 40

Answer 2

Answer:

40 apps

Step-by-step explanation:

8 apps per 12 seconds is a rate of 8/12 (apps/sec) = 2/3 (apps/sec)

2/3 (apps/sec) × 60 (sec) = 40 (apps)
