Question

in a total time of 40 seconds, beetle R ran in a straight line for 30 cm and bumped into beetle J, then beetle J ran for another 90 cm at 3 times the rate of beetle R. What was the rate of each beetle?

Answer 1

beetle R --> 30cm/40 sec = 0.75cm/sec

beetle J --> 0.75*3 = 2.25cm/sec

I believe this is what it is asking...

Answer 2
