Question

un cal a alergat 5,4km in 10 minute. cu ce viteza a alergat calul​

Answer 1

v= d/t

(distanta supra timp)

t=10 min =10:60h=1/6h

$\bf\green{v = \frac{d}{t} }= \frac{54}{10} km \div \frac{1}{6} h \\ \\ \bf \: v = \frac{54}{10} km \times \frac{6}{1} \\ \\ \bf \: v = \frac{324km}{10h} \\ \\ \boxed{ \bf \: v = 32.4 \frac{km}{h} }$
