It takes you 4.8 hours to reach New York
Step-by-step explanation:
The given is:
- It is 240 miles from Boston to New York
- You drive at a speed of 50 mph
We need to find how long would it take you to reach New York
Distance (d) = speed (v) × time (t)
∵ The distance between Boston and New York is 240 miles
∴ d = 240
∵ You drive at a speed 50 miles per hour
∴ v = 50
- Substitute these values in the rule of the distance above
∴ 240 = 50 × t
- Divide both sides by 50
∴ 4.8 = t
∴ The lime of the trip is 4.8 hours
It takes you 4.8 hours to reach New York
