You can put this solution on YOUR website! Let x be the speed of simth's bike
70(0.5+x)=45(x+5)
35+70x=45x+225
70x=45x+190
25x=190
x=7.6
<7.6+5 = 12.6> Therefore simth was travelling at 7.6mph and jones was travelling at 12.6mph ... Or if that doesn't work I have another solution for it.
45=35+x+5
45=40+x
x=5
5+5=10, Therefore simth was travelling at 5mph and jones was traveling at 10mph
