Answer: 2.) 301 miles (3) 30 minutes
Explanation:
2)
Distance traveled per gallon of petrol = 43 miles
Distance traveled on 7 gallons ;
43 × 7 = 301 miles
3)
time taken to cover distance = 45minutes = 45 / 60 = 0.75 hour
Speed of travel = 80km/hr
Recall:
Distance = Speed × time
Distance = 80km/hr × 0.75hr = 60km
Therefore, time required to cover the same distance at 120km/hr equals :
Time = distance / speed
Time = 60km / 120km/hr = 0.5 hr
= 0.5 × 60 = 30 minutes
It is True that artificially acquired passive immunity is conferred when one receives immune serum for poisonous snake bites.
Antivenom injection have performed antibodies against snake poison. So using antivenom injection is develops artificial aquired passive immunity
