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
