Question

an airplane trip flies for 1/3 hours with a constant speed of 12m/hr and another 40 minutes with a constant speed of 804miles/hour what distance did it cover ?


plz do clear explanation

Answer 1

Speed = distance ÷ time
12= d ÷1/3 |multiply both sides by 1/3
d= 4miles

40 mins ÷ 60= 2/3 hrs
Speed=d ÷ t
*804=d ÷2/3 |multiply both sides by 2/3
d=536

4+536=540 miles

*not sure if you meant 80.4miles/hour if so d=53.6 and total distance =57.6 miles
