Question 119478
distance = rate x time
time in sec = (distance in km) / (rate in km/sec)
{{{t = 1280 / 297600}}}
{{{t = 1.2*10^3 / (2.976*10^5)}}}
{{{t = (1.2/2.976)*10^3*10^(-5)}}}
{{{t = .403226*10^(-2)}}}
{{{t = 4.03226*10^(-3)}}} sec
I rounded the answer to 6 places because the speed is given to 6 places
