Question

A train is moving at a uniform speed of $75\frac{km}{hour}$

How far it will travel in $20minutes$

Answer 1

Step-1: Convert Speed into $\frac{km}{minutes}$

$75\frac{km}{hour}$$=\frac{75km}{60minutes}$( As $1hour=60minutes$)

Step-2: Find the distance traveled in $20minutes$

Distance traveled in $60minutes=75km$ ( As speed is $\frac{75km}{60minutes}$)

Distance traveled in $1minute=\frac{75}{60}$

Distance traveled in $20minutes$ $=\frac{75\times 20}{60}$$=\frac{1500}{60}$( simplify $\frac{1500}{60}$by dividing a common factor $60$ in numerator and denominator separately)

Distance traveled in $20minutes$$=25km$

Hence, the distance traveled in $20minutes$$=25km$
