Mark cycles from house to school at a speed of 16 kilometers per hour. he cycles back on the same route at a speed of 15 kilometers per hour. the total time taken for the journey is 73/4 hours. given that the distance from his home to school is d kilometers, and distance = speed times time, write and solve an equation to find the total distance traveled by him.



speed while going to school from house = 16 km/hour

speed while coming back home from school = 15 km/hour

total speed = 31km /hour

time taken = 73/4 hours

distance = speed * time

 = 31 km/hour *(73/4 )hours

= 2263/4 km

= 565.75 km
