(i) In how many hours would it complete to download the whole file?
(ii) How much file does it download in 1 minute?
(iii) How much file is left to download if it downloaded only for 90 minutes?

Answer 1

Step-by-step explanation:

1 part = 40 min

there fore 3part means the whole file=

$40 \times 3 = 120$

= > 2 hours

(ii)=> 1 minute =

$\frac{3}{40} = 0.075$

0.075 part.

iii)=>

$0.075 \times 90 = 6.75 = \frac{6.75}{3} = 2.25$

=> therefore in 90 minutes 2.25 part is completed
