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
