Question

Find the fourth proportional for :
a) 1hour 10 mins
b) 16 hours

Answer 1

Answer:

2 hr 40 min

Step-by-step explanation:

first we convert all inputs in minutes

we know 1hr = 60 minutes

thus we get

60 : 10 :: 960 : x

x =  (960 * 10) / 60

  = 9600/60

  =  160 minutes

which is equal to 2 hour 40 min

Hope this helps!
