Answer:
A) 46 mph
Explanation:
Step 1: To find the speed, you need to find the distance and time to travel between Chicago and Cleveland.
Distance = 354 miles
Time = 9: 50 am to 5: 30 pm
Time = 7 hours 40 minutes
Step 2: Convert time to hours
1 hour = 60 minutes
40 minutes = 60/40 = 2/3 hours
Step 3: Find the speed
Speed = Distance/Time
Speed = 354/7 + 2/3
Speed = 1062/23
Speed = 46.17 miles per hour rounded off to 46 mph
Therefore, A is the correct answer.
