Answer 1

Rajeev ended his delivery trip on Thursday at 1:30 p.m., after driving for 24 hours, unloading for 12 hours, and resting for 30 hours.

Step-by-step explanation:

Rajeev's delivery trip began on Tuesday at 7:00 a.m. and ended when he returned to the truck terminal. Let's break down the information given:

Driving time: Rajeev drove 1,200 miles at an average speed of 50 miles per hour. To find the driving time, we divide the distance by the speed: 1,200 / 50 = 24 hours.

Unloading time: The unloading time is half of the driving time. So, the unloading time is 24 / 2 = 12 hours.

Resting time: Rajeev rested for 30 hours.

To find out when Rajeev ended his delivery trip, we need to add the driving time, unloading time, and resting time to the starting time of the trip:

Starting time: Tuesday at 7:00 a.m.

Driving time: 24 hours

Unloading time: 12 hours

Resting time: 30 hours

Add all the times together: 7:00 a.m. + 24 hours + 12 hours + 30 hours = 73.5 hours

Since there are 24 hours in a day, we can subtract 24 from 73.5 to find the time after the starting day: 73.5 - 24 = 49.5 hours.

This means that Rajeev ended his delivery trip on Thursday at 1:30 p.m.

Answer 2

Rajeev ended his delivery trip on Wednesday at 49.00 hours after leaving the terminal on Tuesday.

Step-by-step explanation:

Calculate driving time:

Time = Distance / Speed

Driving time = 1,200 miles / 50 miles/hour = 24 hours

Find unloading time:

Unloading time = Driving time / 2 = 24 hours / 2 = 12 hours

Total travel time:

Travel time = Driving time + Unloading time + Resting time

Travel time = 24 hours + 12 hours + 30 hours = 66 hours

End time:

Rajeev started at 7:00 a.m. on Tuesday, so add the travel time:

End time = Start time + Travel time

End time = 7:00 + 66 hours = 49:00 on Wednesday

Therefore, Rajeev finished his delivery trip on Wednesday at 49.00 hours (almost noon).
