10 minutes after travelling each 70 km. In what
time it will travell 728 km?
(1) 14 hours
(2) 14 hours 28 minutes
(3) 14 hours 40 minutes (4) 13 hours 38 minutes (5) None​

Answer 1

Answer:

I think answer should be 5) None

Step-by-step explanation:

Speed = Distance / Time

Time = Distance / Speed

= 728/56

Time = 13 hours

728/70 = 10.4

10.4 * 10 = 104 minutes

104 minutes = 1 hour 44 minutes

13 hours + 1 hour 44 minutes = 14 hours 44 minutes

Thus the answer is none of the above option

But I think you can select the 4th option as well
