Question 764295
two cars will run for 10 kilometers,
car A started 7 1/2 kilometers ahead,
 car B started at 0 kilometers,
 what will be the speed of two cars if they reach 10 kilometers
 at the same time?
:
Not enough information to find the actual speed, but we can find
the relationship between the two speeds
{{{2.5/A}}} = {{{10/B}}}
Cross multiply
2.5B = 10A
B = 10A/2.5
B = 4A
:
B's speed is 4 time A's
