1.34: A motorist starts and drives at a constant speed \(\displaystyle V_1\, \mbox{km/h}.\) After \(\displaystyle t_1\) hours, another driver starts from the same location and drives along the same road at constant speed \(\displaystyle V_2\, \mbox{km/h},\) where \(\displaystyle V_2\, >\, V_1\) and, after another \(\displaystyle t_2\) hopurs, catches up with the first driver.

(a) Derive a formula for calculating \(\displaystyle t_2\) when \(\displaystyle V_1,\, V_2,\) and \(\displaystyle t_1\) are known.

Thanks for the help everyone. I finally understand how to solve this. I think I found this problem hard since I wasn't familiar with the formula:

D = rΔt

Solution:

V1(t1+t2) = V2(t2)

t2=(V1t1)/(V2-V1)
