Question

A truck can travel a distance of $471\dfrac{3}{4}km$in $18\dfrac{1}{2}$hours. What is the distance travelled by truck in 1 hour?

Answer 1

This is a quite simple question. We have already learnt that velocity or speed of an object is the distance travelled by an object in a particular period of time. Apply this concept in the equation. Also given that the distance travelled by a truck is $471\dfrac{3}{4}km$in $18\dfrac{1}{2}$hours. Hence to calculate the distance travelled in one hour we just need to divide the distance travelled by the given time.

Complete step-by-step solution:
Given that,
The distance travelled by the truck= $471\dfrac{3}{4}km$ $=\dfrac{1887}{4}km$
Time taken by the truck to travel
$471\dfrac{3}{4}km$=$18\dfrac{1}{2}$hours$=\dfrac{37}{2}hours$
Thus the distance travelled by the truck in 1 hour
$=\dfrac{\dfrac{1887}{4}km}{\dfrac{37}{2}}$
$=25.5km$
Therefore the distance travelled by the truck in 1 hour is 25.5km.

Note: We can interpret the term distance as the path travelled by an object from initial to final point for a particular period of time. Also remember that the distance is a scalar quantity. While the displacement is a vector quantity and it is the shortest distance between any two points,
In earlier times there are different types of units used for measurement. Three of them are CGS, FPS and MKS units. But the internationally accepted unit for the measurement is system international or simply S.I units. In this measurement there are 7 basic units. That is, the S.I unit of distance is metre, for time it is second and for velocity it is metre per second.
