Question

Steve travels 3 times faster than Mike. Traveling in opposite directions, they are 170 miles apart after 2.5 hours. Find their rates of travel.

Answer 1

let x the the rate of travel of Mike, (3x+x)*2.5 = 170
4x=68
x=17miles/hour
therefore Mike travels at 17miles/hour while Steve travels at 51miles/hour

Answer 2

How did you figure it out? Every time I've done it, the computer says it's wrong. I think I'm missing a step.

Answer 3

what do you mean?

Answer 4

(3x+x)*2.5 = 170 is actually from speed x time = distance and they travel in opposite direction so i just take the time as the common factor

Answer 5

let speed of Mike = x mph
Then speed of Steve = 3x mph

In 2.5 hours
Mike covers distance = x * 2.5 = 2.5x
Steve covers distance = 3x * 2.5 = 7.5x

ATQ 2.5x + 7.5x = 170
10x = 170
so
x = 17 mph
so
Mike travels at 17 mph
and
Steve travels at 3*17 = 51 mph

Answer 6

Okay, I get it now. Thank you.
