Answer:
349.5miles
Step-by-step explanation:
Given
Initial time =150min =2.5hours
Initial speed =75mph
Distance = speed x time
Distance = 75*2.5
Distance = 187.5m
Final time =2hours
Final speed =81mph
Distance = speed x time
Distance = 81*2
Distance = 162m
Total distance = initial +final
Total distance = 187.5+162
Total distance = 349.5miles
