    I am totally lost, because there is no distance or time given

    (30mph*t1+40mph*t2)/(t1+t2) which reads total distance over total time thats all i can think of

    ok using 30mph*t1=40mph*t2 i said 30mph*t1+30mph*t1=30mph*t1+40mph*t2 in the denominator and t1+t2=t1+(30/40)*t1 in the numerator so we have (t1(30*2))/(t1(1+3/4)) numerator/denominator however they both have been written in terms of t1 therefore can cancel to get 30*2/1.75 which equals 34.29
