a train moves at a constant speed of 80 km/h for 2.5 hours. how far does the train travel?
answer

Explanation:

Step1: Recall speed - time - distance formula

The formula is $t=\frac{d}{v}$, where $t$ is time, $d$ is distance and $v$ is speed.
Given $v = 24$ km/h and $d=72$ km.
$t=\frac{72}{24}$

Step2: Calculate the time

$t = 3$ hours

Step1: Recall speed - time - distance formula

The formula for average speed is $v=\frac{d}{t}$, where $v$ is average speed, $d$ is distance and $t$ is time.
Given $d = 150$ km and $t = 3$ hours.
$v=\frac{150}{3}$

Step2: Calculate the average speed

$v = 50$ km/h

Step1: Recall speed - time - distance formula

The formula is $d=v\times t$, where $d$ is distance, $v$ is speed and $t$ is time.
Given $v = 80$ km/h and $t = 2.5$ hours.
$d=80\times2.5$

Step2: Calculate the distance

$d = 200$ km
