Answer:
42. 2½ or 5/2 hours
43. 70
Step-by-step explanation:
42. Speed = Distance/Time
Substitute the values.
80kph = 200km/time
2.5hours = time
2.5 = 2½ or 5/2
43. Speed = Distance/Time
20kph = distance/3.5hr.
70km = distance
Since it says only the answer, then we disregard the measurement. So, it is just 70.
