Linear word problems
Please help me solve this problem by coming up with a linear algebra equation:
A biathlon event involves running and cycling. Kim can cycle 30km/h faster than she can run If Kim spends 48 minutes and a third as much time again cycling in an event that covers a total distance of 60 km, how fast can she run?
Formula: distance= speed * time
dont know if this is right for sure, let me know x-48 1/3 =30

what i meant was x-48 1/3 /2 = 30

Hi masters, my interpretation of the problem is different to yours but your interpretation is actually the correct one.

Thankyou so much (Rofl)
