Answer:
90/1.5=60 mph
Step-by-step explanation:
I assume that the train is traveling at constant speed.
Between 12:45 pm and 2:15 pm the train has traveled 180-90=90 miles. So 90 miles in 1.5 hours which means that its speed is 90/1.5=60 mph
You set up a proportion. first, put the percent so if it's 30 percent, it would be 30 over 100. Then, set up the second part. is over of.
The answer is 240 :3
60+60= 120
120+60 = 180
and 60 more would be 240
60 fours would be 240
3 60's would be 180. So your answer is 240
