Question

Please explain how to do this. tried to solve but cant do it

Answer 1

Answer:

2.55km

Step-by-step explanation:

$d=st$

where:

   d=distance

   s=speed

   t=time

$s=\frac{3.4 \ \text{km}}{\text{hr}}$

$t=0.75 \text{hr}$

$d=st=(\frac{3.4 \text{km}}{\text{hr}})(0.75 \text{hr}})=2.55 \text{km}$

Answer 2

Answer:

$3\frac{2}{5}$ × $\frac{3}{4}$ $= 2\frac{11}{20}$ km

         = 2.55 km
