Sagot :

Answer:

1. 1:50 PM

2. 4 hours and 35 minutes

3. 619.42 km/h

Step-by-step explanation:

1. 13:50 minus 12 hours, which will give an answer of 1:50 PM.

2. 13 h minus 9 h is equal to 4, then, 50 min minus 15 min is 35. Thus, its 4 h and 35 min.

3. Convert 4 hours and 35 minutes to a fraction representing hours. Then, we divide 2,839 by 55/7, which will yield an answer of 619.41818 or 619.42 km/h.
