Question

Grace thought that a plane journey would take 7/10 hr but the actual journey took 1/5 hr longer. How long did the actual journey take?​

Answer 1

Answer:

Firstly leta tranform the hours to minutes,

To convert hours to minutes, we multiply it by 60.

Therefore, (7÷10) ×60, zero of ten and sixty cancels out leaving us with 7×6 = 42 min.

1 by 5 hours, i. e. (1÷5)×60 = 12 minutes.

Therefore total journey took

42+12= 54 mins.

To convert it to hours, divide it by sixty,

Giving you 0.9 hours, or 9/10 hours.
