Question

Use the formulla d=rt.find t for r =48.3m/h and d=545.79m.

Answer 1

If you solve d = rt for t, you have t = d/r.  If we have values for d and r we will fill them into that equation and divide.  $\frac{545.79m}{48.3 \frac{m}{h} }$.  Setting that up so the meters cancel as they should looks like this: $545.79m* \frac{h}{48.3m}$ lets us divide as we need to and at the same time cancel out the distance, leaving us time in hours.  The t value then is 11.3 hours.
