A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 11 hours?
Scorpion4ik [409]

Answer:

The jet will cover 2585 miles in 11 hours.

Step-by-step explanation:

Given that:

Distance travelled by jet in 2 hours = 470 miles

Speed of jet = \frac{Distance}{Time}

Speed of jet = 470/2

Speed of jet = 235 miles per hour

Time = 11 hours

Distance travelled in 11 hours = Speed * Time

Distance = 235 * 11

Distance = 2585 miles

Hence,

The jet will cover 2585 miles in 11 hours.

A high-speed bullet train travel 900 feet in 5 seconds at this rate how far would it travel in 1 minute
iragen [17]
Since there are 60 seconds in one minute, we can form the equation:
900 \div 5 = x \div 60
From here, we can cross multiply.
5x = 54000
x = 10800
The train would travel 10,800 feet in one minute.
