Michael and Jennifer make their way through the damp and dark evening towards Joe\'s house. Michael had left his books at Joe\'s house and needed them for the weekend. The heavy snows caused downed trees that closed some local roads, so they took at 12 ½ mile detour. Jennifer hardly noticed the roundabout route they traveled to Joe\'s. She wanted to get to the 8:15 movie where they were meeting friends. She was anxious to get there. Jennifer said: Michael! It\'s 7:40. How much farther until we get there? I\'ve been wanting to see this movie for months and we can\'t be late!\" Michael gave her a glance and mumbled something about the roads. Finally, they reached Joe\'s, but the house was dark. \"Great - all this way and no one home! You should have called first!\" Michael replied \"Relax! I know they leave the back door unlocked.. Come on in with me.\" As they approached the living room, the clock struck eight. The lights flashed on and Jennifer hears voices yell \"Surprise!\" Michael and some friends had planned the party the celebrate Jennifer\'s birthday.

1. Michael and Jennifer left at her house at 7:15 p.m. to head for Joe\'s. How long did they take to get here?

2. Michael traveled 4.3 miles before reaching the detour point. How many miles did he actually drive to reach Joe\'s house, including the detour?

3. When Michael and Jennifer drove home, they were able to take the normal route, 7.8 miles. How far did Michael drive on the round trip to Joe\'s and back to Jennifer\'s house?

I NEED EXPLNATION AND DETAILS

Solution

Part A

Michael and Joe Left at her house at 7:15 PM

Consider the following statement \"As they approached the living room, the clock struck eight\"

This implies, both of them reached Joes House at 8PM.

Therefore, it took them 45 minutes to reach Joes House.

Part B

Consider the below statement

\"The heavy snows caused downed trees that closed some local roads, so they took at 12.5 mile detour\"

Distance travelled by Michael on the detour is 12.5 miles

Distance travelled by Michael prior to reaching Detour Point is 4.3 miles

Therefore, Total Distance Travelled by Michael to reach Joes House is 12.5+4.3=16.8 miles

Part C

Distance Travelled by Michael to reach back at Jennifers house is 7.8 miles

Total Distance Travelled on the round Trip is 7.8+16.8=24.6 miles
