Question

if vaishalee goes to school from her house at the speed of 40 km per hour and reaches in 8 minute find the time of reaching to school from house if she moves at a speed of 36 km per hour

Answer 1

Answer:

Step-by-step explanation:

speed of vaishallee = 40km/hr

time = 8min = 8/60 = 2/15hr

distance = speed x time = 40 x 2/15 = 16/3 km

now, distance = 16/3 km

speed = 36km/hr

time = distance / speed = 0.14hr = (0.14x60)min = 8.40min
