Question 889137
Two cars travel the same distance. The first car travels at a rate of 37 mph and reaches it's destination in t hours. The second car travels at a rate of 56 mph and reaches it's destination in 2.8 hours earlier than the first car. How long does it take the first car to reach it's destination
***
let t =How long does it takes the first car to reach it's destination
t-2.8=How long does it takes the second car to reach it's destination
distance=rate of speed*travel time
..
37t=56(t-2.8)
37t=56t-156.8
19t=156.8
t≈8.25
How long does it takes the first car to reach it's destination=8.25 hrs
