Question

Two trucks started toward each other at the same time from towns 500 km apart. One truck traveled at a rate of 65 km per hour while the other traveled at 60 km per hour. After how many hours did they meet?

If x represents the number of hours, which of the following equations could be used to solve the problem?
a.65x=60x
b.65x-60x=500
c.65x+60x=500

Answer 1

(Ans):(c) 65x+60x=500

Analysis:

Let, the time be,'x'

By condition,

(65*x)+(60*x)=500

or, 65x+60x=500

or, 125x=500

or,x= 500/125

or, x=4

So, they will meet after 4 hours.
