In 3 hours Tom drives 243 miles.
What is speed?
- The rate at which an object's position changes in any direction.
- Speed is defined as the ratio of distance traveled to time spent traveling.
- Because it has only one direction and no magnitude, speed is a scalar quantity.
So, to find how many miles Tom can drive in 3 hours:
Given: Tom drives 81/2 miles every 1/30 hour.
- 81/2 miles = 40.5 miles
- 1/30 hours = 30 minutes
So, in 30 minutesTom drives 40.5 miles.
- Then, in 1 hour Tom will drive 40.5 + 40.5 = 81 miles.
- Miles Tom will drive in 3 hours = 81 × 3 = 243 miles.
Therefore, Tom drives 243 miles in 3 hours.
