The table shows how far an airplane travels over time. what is the speed of the plane in miles per hour? distance (mi) 60 180 540 660 time (min) 10 30 90 110 6 mph 300 mph 360 mph 600 mph

C.360 mph

Step-by-step explanation:

We are given that distance in miles and time in min

We have to find the speed of plane in miles per hour

Distance (in miles):60 180  540 660

Time(in min):          10   30    90  110

Total distance travels by airplane=60+180+540+660=1440 miles

Total time =10+30+90+110=240 minute

Time in hours ==4 hours

Speed=

Speed of plane =[tex]\frac{1440}{4}=360 miles/hour

Hence, the speed of the plane =360 mph

Therefore, option C is true
