EXPLANATION
IQ3. A train leaves from station A at 10:00 AM and arrives at station B at 11:00 PM. If the train travels at a speed of 60 miles per hour, how far apart are stations A and B?
a) 60 miles
b) 480 miles
c) 540 miles
d) 780 miles
ANSWER: d) 780 miles
EXPLANATION:
To find the distance between stations A and B, we need to determine the time taken by the train to travel from 10:00 AM to 11:00 PM, and then multiply that time by the speed of the train.
The time elapsed from 10:00 AM to 11:00 PM is 13 hours because there are 12 hours from 10:00 AM to 10:00 PM, and an additional hour from 10:00 PM to 11:00 PM.
Now, we can calculate the distance using the formula:
Distance = Speed × Time
Distance = 60 miles/hour × 13 hours
Distance = 780 miles
Therefore, stations A and B are approximately 780 miles apart.
