Question

During a 980-mile cruise, a ship traveled 590 miles in 7 hours initially. What was the speed for the rest of the trip if 13 hours were spent on the whole cruise?

A. 40 mph
B. 45 mph
C. 50 mph
D. 55 mph

Answer 1

To find the speed for the rest of the trip, we can set up an equation using the total time spent on the cruise. Solving for the unknown speed, we find that it was approximately 65 mph.

Step-by-step explanation:

To find the speed for the rest of the trip, we need to first calculate the total time spent on the cruise. Since 590 miles were covered in 7 hours initially, we can find the total time spent using the formula:

1. 
   
3. Initial Time = Distance / Speed
4. 
   
6. Total Time = Initial Time + Rest of the Time

Let the speed for the rest of the trip be represented by x. We can set up the equation:

7 + Rest of the Time = 13

Simplifying, we get:

Rest of the Time = 13 - 7 = 6 hours

Using this time and given distance, we can calculate the speed for the rest of the trip:

x = Distance / Time

x = (980 - 590) / 6

x ≈ 65 miles per hour

Therefore, the speed for the rest of the trip was approximately 65 mph.
