<PRE><B>Question 333584</B>
If I can drive 630 miles in 10.5 hours, how many miles can I drive in 4 hours?
:
You can use a simple ratio equation, let d = dist in 4 hr
{{{d/630}}}={{{4/10.5}}}
Cross multiply
10.5d = 630 * 4
10.5d - 2530
d = {{{2520/10.5}}}
d = 240 miles
:
:
You can confirm this by finding the speed
{{{630/10.5}}} = 60
 60 * 4 = 240 mi</PRE>
