Abicyclist traveled with a speed of 12 km/h from a camping ground to a station, located 60 km away. write a formula expressing the dependence of the variable s on t, where s is the distance between the bicyclist and the station in km, t - the duration (time) of his travel in hours. using the formula, find s for t=3.5 and t for s=30 (and = separate)

Let

s-------> is the distance in Kilometer

V-----> the speed of the bicyclist in Km/h

t------> is the time in hours

we know that

in this problem we have

Part a) Find s for

we know that

solve for s

substitute the values

therefore

the answer Part a) is

Part b) Find t for

we know that

solve for t

substitute the values

therefore

the answer Part b) is

nope

step-by-step explanation:

do you mean add both of the equations together

because if you do the answer is 10x-5
