Question

a cyclist travels 40 km at a speed of x km/h. Find the time taken in terms of x. Find the time taken when his speed is reduced by 2 km/h. if the difference between the time is 1 hour, find the original speed x. STEP BY STEP PLZ

Answer 1

Answer:

5 hrs , 10 km/hr

Step-by-step explanation:

original speed = x km/hr ,new S =( x -2) km/hr

difference in time taken = 1hr , d/s = t

40/(x- 2)} - 40/x = 1

x = 10 km/hr (original speed)

time taken when speed was reduced by 2 km/hr = 40/8= 5 hrs
