A car 8

A car begins heading along a path at 50 mph. A second car begins an hour later, along the same path traveling at 70 mph. For how long will the first car traveled when the second car overtakes it?

Correct answer:

x =  175 km

Step-by-step explanation:

v1=50 mph v2=70 mph T=1 h x=v1 t = v2 (tT)  v1 t=v2 (tT) 50 t=70 (t1)  20t=70  t=2070=3.5  t=27=3.5  x=v1 t=50 3.5=175 km
