Question

Matt took a train traveling at an average speed of 80 mph from Boston, MA to Washington, D.C. The trip took 6 hours. On his way back to Boston, Matt decides to take an express train that travels at an average speed of 100 mph. How long will the trip home take?

Answer 1

4.8 hours (4 hours and 48 minutes)

First, find the total distance of the trip by multiplying the rate (80mph) by the time (6 hours). This is 480 miles, which is the total distance. If the express train travels at 100mph, then the total time it takes is 480/100, or 4.8 hours.

Answer 2

Answer:

The trip will take 4.8 hours

Step-by-step explanation:

Firstly, we need to calculate the distance from Boston to Washington

Mathematically:

Distance = speed * time

Distance = 80 mph * 6 hours = 480 miles

Now we want to calculate the time it will take a train that travels at a speed of 100 mph

Mathematically;

time = distance/speed

time = 480/100 = 4.8 hours
