Final answer:
To find out how much more the student has to drive to reach their friend's city after having already covered a part of the journey, simply subtract the distance traveled, 56.55 km, from the total distance, 100 km, which gives a remaining distance of 43.45 km. Option b) 1 hour 1minute because it's a little over an hour left to drive.
Step-by-step explanation:
The question asks: "We have to drive 100 km to reach our friend's city. By 4 p.m. we had driven 56.55 km. How much more do we have to drive?"
To solve this, we need to subtract the distance already travelled from the total distance required to reach the destination.
- Total distance required to reach the destination: 100 km
- Distance already travelled: 56.55 km
We calculate the remaining distance as follows:
100 km - 56.55 km = 43.45 km
The remaining distance to drive is 43.45 kilometers.
The closest option is Option b) 1 hour 1minute
Option b) 1 hour 1minute because it's a little over an hour left to drive.
