Question

4 hours 20 min +6 hours 40 min​

Answer 1

Answer:

How do I convert 7 hours and 20 minutes into hours?

Two ways.

[1] Working with HOURS.

T = 7 h 20 min = H + M

H = 7 h

M = 20 min, but 1 min = h/60, then M = 20 . h/60 = 20/60 h = 1/3 h = 0.33.. h

T = H+M = 7 1/3 h = 7.33.. h

[2] Working with MINUTES

T = 7 h 20 min = H + M

H = 7 h, but 1 h = 60 min, then H = 7 . 60 min = 420 min

M = 20 min

T = H+M = 440 min

or T = 440 . h/60 = 7.33.. h

Answer 2

Answer:

11 hr

Step-by-step explanation:

4 hr + 6hr = 10 hr

20 min+40min= 1hr

so 10+1=11hr
