Question

So a moped travels at 40km/h for part of a trip and 10km/h for the remainder. If it takes 5.75 hours to travels 185km, how far did it travel at each speed?
40x +10(5.75 -x) = 185

distance = rate times time for each part of the trip

40x + 57.5 -10x = 185

30x = 185 - 57.5

can you finish from here? find x then find 5.75 -x

to find the distance traveled - multiply those results by the speeds given above.
